GroLine Waterproof EC/TDS Meter Pen

The latest pocket meter for measuring the EC/TDS of a hydroponic nutrient solution. This modern-looking meter is only 0.7″ thick and extremely ergonomic, fitting comfortably in your hand. The HI98318 has a very large easy-to-read LCD display that shows both EC or TDS and temperature along with calibration, stability, and low battery indicators. All operations are simplified to two buttons. One is for turning the meter on/off and the other for automatic one-point calibration.

How to Use:

Automatic calibration is achieved easily. Simply submerge the sensor in calibration solution and the meter will automatically detect the calibration standard (5.00 mS/cm in Quick Cal mode or 1.41 mS/cm in standard calibration mode). Temperature is automatically compensated for with the integrated temperature sensor.

Features:

Waterproof
Fast Automatic Temperature Compensation with exposed temperature probe
Graphite sensors that reduce polarization effects
0.5 (500 ppm) and 0.7 (700 ppm) selectable EC to TDS conversion factors
Single point automatic calibration using Quick Cal standard or 1.41 mS/cm in standard calibration mode
250 hour battery life
