Direct digital readout displays instantaneous sensor output of 15 second averages. Measures µmol, lux k lux or Wm-2. Meter automatically selects range with best accuracy and resolution for a given input signal so that measurements can be made in a variety of light environments. High quality amplifier provides automatic zeroing capability and long term stability. Calibration multipliers can be entered easily, and two sensor multipliers can be stored in memory. HOLD key allows you to retain current reading or switch to measurement mode for continuous update of display. Low battery indicator. Automatically shuts off after 20 minutes of inactivity. Avoid contact with water. Sensors sold separately.

For use with the Li-Cor® LI-1500 Light Sensor Logger (sold separately) to measure underwater or atmospheric photosynthetic photon flux density. Measures PAR in the 400-700 nm waveband using a Silicon Photodiode and glass filters encased in a waterproof housing. Typical output is in umol s-1 m-2. For use in freshwater or saltwater in pressures up to 800 psi (5,500 kPa, 560 meters depth). Requires underwater cable and lowering frame (each sold separately).
2-wire shielded cable for use with underwater sensors. Waterproof connector on the sensor. BNC connector attaches to readout instruments. For Type “SA” sensors (also attaches to the Calconnector of Type ”SB” sensors).
Provides stability for the proper orientation of the sensor or sensors and minimizes shading effects. Anodized aluminum frame measures 51.4cm (20.3”) L x 35.6cm (14.0”) W and weighs 327g (0.72 lbs).
For use with the LI-250A Light Meter or LI-1500 Light Sensor Logger (each sold separately). Measures underwater photon flux from all directions in saltwater or freshwater. Requires underwater cable and lowering frame (each sold separately).
For use with the LI-250A Light Meter or LI-1500 Light Sensor Logger (each sold separately). Measures Photosynthetically Active Radiation (PAR) accurately in natural and artificial light. Features a 2m cable.
For use with all LI-COR terrestrial-type sensors. Features an anodized aluminum base, stainless steel leveling screws, and a weatherproof spirit level. Measures 3” in diameter and weighs 0.21 lbs.
