Combo waterproof testers are designed for high accuracy pH, EC/TDS and TEMPERATURE measurements. No more switching between meters, the Hanna Instruments' Combo does it all. All pH and EC/TDS readings are automatically temperature compensated(ATC) for. The EC/TDS conversion factor is user selectable as well as temperature compensated with coefficient B. The Combo is waterproof, floating and has a large easy-to-read dual-level LCD and automatic shut off. The Combo has a replaceable pH electrode cartridge with a cloth removeable junction as well as an EC/TDS graphite electrode which resist contamination by salts and other substances that come in contact with the electrode. Fast, efficient, accurate and portable, the Combo pH, EC/TDS and Temperature tester meets the requirements of multi-routine measurements.
Some of the Combo's outstanding features include:
* Completely waterproof, can be fully immersed in water, and it floats.
* Easy-to-read Custom Dual-level LCD.
* Automatic Temperature Compensation, User selectable Beta(B) of 0.0 to 2.4%
* Replaceable pH electrode cartridge.
* Stability Indicator.
* User Adjustable TDS Ratio (0.45 to 1.00 in 0.01 steps)
* Battery Level Indicator.
* Automatic calibration - with 2 sets of memorized cal solutions.
