Pocket Waterproof EC, pH and TDS (Low Range) tester

Multiparameter pH, EC, TDS and °C Tester

Part no: HI 98129 (low range)

Part no: HI 98130 (high range)

HI 98129 and HI 98130 are waterproof testers that offer
high accuracy pH, conductivity, total dissolved solids
and temperature measurements in a single meter.

No more switching between meters for routine measurements:

• These floating, waterproof combination testers have an easy to read display and automatic shut-off
• pH and EC/TDS readings are automatically temperature compensated
• The EC/TDS conversion factor is user selectable as well as the temperature compensation coefficient
• Both testers feature a replaceable pH electrode cartridge together with an EC/TDS graphite electrode
• Automatic shut-off helps preserve battery life
• Replaceable pH cartridge extends life of the tester – when pH sensor is exhausted, simply replace it with a new one
• Calibrate direct into Hanna buffer solution sachets
• Automatic 1 or 2 point pH calibration
• Rubberised keyboard
• Quick and easy to operate
• Easy switch between Celsius & Fahrenheit readouts
• HOLD function
• Easy to replace pH electrode cartridge with sturdy snap-in connector means there are no pins to bend or break
• Large LCD display
• pH and temperature displayed simultaneously
• Automatic temperature compensation
• BEPS Battery Error Prevention System
• Floating waterproof casing with tactile grip makes testing easier and less of a headache
• Removable safety cap

Main benefits:

• On-screen battery life
• LCD indicates the percentage of battery power remaining at startup
• Instability & ATC indicators
• Ensures reliable EC and TDS measurements. ATC symbol is shown when active
• Adjustable temperature coefficient factor
• Users can choose between different BETA (B) factors for precise temperature compensated measurements
• HOLD function
• The HOLD function freezes the LCD display temporarily
• Standard or N.I.S.T buffer calibration
• Automatic calibration is performed with 2 sets of memorised buffers for greater accuracy
• Adjustable TDS ratio
• For measurement accuracy, users can choose between different conductivity to TDS conversion factors

High accuracy EC/TDS graphite probe

The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution.
The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings
