PAR Sensor Multimeter Amplifier - Apogee SQ-500 and LiCor

Made in the USA. Flat Rate Shipping.

Directly connect your Apogee Instruments SQ-500 PAR/PUR sensor to your multimeter for a fraction of the price.

The SQ-500 sensor is the next generation PAR meter from Apogee. However, its very low signal levels prevents its use with most low-cost multimeters. This SQ-500 amplifier board allows you to directly connect and read PAR from any multimeter capable of reading 1mV in either the volt or millivolt range.

  • Compatible with most hand-held multimeters - plugs directly into the test lead bannana jacks on the front panel (0.75inch spacing - industry standard)
  • For use with the Apogee SQ-500 sensor head - directly attach all three wires to the provided terminal block.
  • Amplifies 10uV (microvolt) signals to milli-volt signals (100x gain)
  • Self-powered by a CR2032 battery (included for US shipments)
  • Full 0-3000PAR range

Simply plug in the Amplifier to your multi-meter, connect the sensor to the terminal block, turn on the amplifier, and switch your multimeter to the 2V or millivolt range to read PAR on the display. If you are using the 2V range, simply ignore the decimal point.
