  • Pricing and availability are subject to change without notice. Quotations are available upon request. All prices are based upon a single item purchase unless otherwise noted. All customers are afforded the same pricing as the current price list. Quantity discounts are determined by PSI Management.
  • Quotations for PSI instrumentation always include pricing, delivery information, validity from the date of issuance, and bank details. Prices do not include shipping and packing costs; those are added as a separate item on the invoice or on the quotation. Prices exclude VAT.
  • Customs clearance and all duties are not the supplier’s responsibility.
  • Custom or special-made equipment is nonrefundable and nonreturnable. It is warranted for workmanship only – PSI cannot guarantee that it will work for the customer’s special purpose.
  • Purchase Orders must include a complete invoice address and shipping address and precise description of ordered items. Once a customer’s purchase order is submitted and accepted, PSI recognizes a contract with the customer for goods to be supplied. PSI is not responsible if shipping date must be extended longer than it was originally quoted (due to unforeseen happenings, such as year-end closing, fiscal year closing etc.). Alteration or cancellation of the purchase may result in additional charges or penalties. PSI is not responsible for items that were ordered incorrectly.
  • Wire transfer is the preferred payment method. It is the quickest and least expensive way to pay for your order. If you have a Quotation or an Invoice from us, that is all that your bank needs to make an electronic money transfer. PSI bank information for wire transfer is provided on the Quotation/Invoice. Please include your name and our Invoice/Quote number in the Wire Transfer reference.
  • Check may be accepted ONLY upon prior approval.
  • Credit card may be used in our Credit Card Payment Gateway. For details, write to ivana(at)psi.cz.
  • Letter of Credit or CAD are unusual form of payment for PSI. Customers wishing to pay by Letter of Credit or CAD must alert PSI about this intent upon submission of the purchase order. PSI will furnish these customers with additional terms and conditions specific to the issuance of the Letter of Credit or CAD.

Shipping policy

Shipping Policy

READ the following instructions before you accept the shipment from the carrier.

  • Inspect the shipment carefully.
  • If you received an evidently damaged shipment, do not accept it from the carrier.
  • If there is no visible damage, open the container and check its contents carefully.
  • It is the customer's responsibility to unpack the parcel and to check its content within 48 hours after delivery. If the damage claim is reported after this time period, PSI will not be able to claim for refund for damaged goods at the shipping company. In such case, any future repair to the damaged goods will be considered as non-warranty repair.
  • If any damage is found in the parcel content within 48 hours after delivery, please contact PSI – support(at)psi.cz.
  • All PSI shipments include a list of shipped instruments and/or additional parts. Please, compare the contents of the shipment and the enclosed list.
  • If concealed damage is found after the shipment is opened, make a written note of any damage (on wrapping, container, contents, etc.) and send it to the carrier and to PSI.
  • Retain all shipping materials for the purpose of damage inspection.

Goods shipped by PSI were delivered to the carrier in good condition. They were packed with great care using standard approved packaging methods. All PSI shipments are insured for the full product value and the carrier is responsible for any damage in transit! Please, report any damage or incomplete shipment to PSI immediately.

Return Procedure

Before returning any instrument to PSI:

  • Make sure that the instrument is in fact faulty and has not just been set up improperly.
  • Contact PSI support(at)psi.cz before sending anything back. You will be given the RMA number, which must be clearly marked on the outside of the shipped container.
  • When sending the faulty device back to PSI, please pack it very carefully. Use a have duty box and lots of wrapping/foaming material.
  • If the returned instrument is damaged during shipment due to insufficient packing, PSI will have to charge the repair (or its part) as a non-warranty one.
  • If you have encountered a program failure, we would need a printed copy of any faults you have seen, including how to reproduce them. Include it into the return package along with your mailing address.
  • Include a copy of the Invoice on which the product was shipped to you.
  • All returns must be shipped prepaid. Unpaid packages will not be accepted.
  • In case of questions contact us by E-mail: support(at)psi.cz or shipping(at)psi.cz, by phone: +420 511 440 034, +420 511 440 032,+420 511 440 022, +420 388 440 046, or by fax: +420 511 440 901.
  • What is the difference in between the LAI-2000 and LaiPen LP 110?
  • LAI-2000 measures the attenuation of diffuse sky radiation at five zenith angles simultaneously, it has five detectors. The correct way of measurement is conditioned by attaching an appropriate view cup to hide foreign objects in the field of view. Our LaiPen is designed to avoid the system of view restrictor cups. This means it has a single view cup and a single detector and the four subsequent angles must be measured separately with the help of build-in electronic inclinometer and visual-acoustic indicator. In LaiPen, the permanent restricting cup has restriction angle 160 along x axis and 1120 along y axis, which is different from LICOR LAI 2000.
  • Can I correct measurements for clumping effects in the LaiPen LP 110?
  • The only measurement you do with LaiPen is irradiance. In this respect, you can not correct measured irradiance values for clumping during measurement, but you can correct your calculation of LAI index afer you download irradiance values from LaiPen to computer.
  • What is the exact geometry/configuration of the ring sensors in the LaiPen LP 110?
  • There are no ring sensors in LaiPen. Instead, the LaiPen device is equipped with a single wide-angle optical sensor used in conjunction with a cup restricting 160 / 1120 angle sector. All angles (in multiple angle measurement mode) are measured only with one sensor. The other four angles are obtained by subsequent inclinations of the device from zenith angle, which is controlled by electronic inclinometer with pre-defined five angle positions.
  • Can I exclude specific rings from the LaiPen LP 110 computation, or change path lengths of different rings (not homogeneous canopy) or measure single trees?
  • In multiple-angle measurement mode you always measure all five angles. But since the data you download from the LaiPen to computer for further processing are only uncomputed raw values, exclusion of any measurement would be possible. It is not possible to change the path lengths - these are fixed. And the single trees measurement, for sure it can be done.
  • The website claims we can measure under different sky conditions with the LaiPen LP 110, but the way the instrument deals with this is unclear?
  • The dual sensor mode of measurement alows to estimate reference values for each particular time of measurement in changing weather conditions much more efficiently than the single sensor mode. The way how single sensor mode of measurement deals with this issue is decribed in the first version of Lai Pen manual (chapter 7.A. Single Sensor Mode of Measurement). The computation in case of dual sensor mode of measurement is described in the second attached file named: “Dual mode_ Introduction.pdf”, which is not included in the first version of manual.
