Detailed Description for Combo - Waterproof pH / EC / TDS / C / F Testers with Replaceable Electrode
Automated Aquarium Systems - Hanna COMBO pH, EC/TDS, Temperature Pocket Meter
"COMBO"
pH
& EC/TDS & Temperature Pocket Meters
DESCRIPTION:
The  HI98130 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.
