• 【IP68 PAR Meter】The quantum sensor of the PAR meter is designed with an IP68 level, and it comes with a 37" Solid Telescopic Pole (Included), it's able to measure the photosynthetically underwater accurately.
• 【High Accuracy】The measurement range of the waterproof PAR meter is from 0~4000 μmol/m2/sec, The cut-on wavelength is 400 nm and the cut-off wavelength is 700 nm with ±10 nm, ensuring accurate results and making plants develop optimally with sufficient light in the aquarium.
• 【Record Function】PAR Meter can record up to 100 measured values, you may easily track and review previous measuring readings, it is particularly useful to track and change the light energy levels for prompt decisions.
• 【Power ON/OFF】Press the Power button to turn on the device. Press and hold the Power button for 3 secondsto tumn off the device. The device will shut down automatically if there is nooperation within 3 minutes.
• 【Broad Application】Our lux meter can be widely used in such as schools, hospitals,factories, airports, light meter photography, families and other occasions of brightness measurement.It's a must-have measuring tool for professionals, academics.
