HI-981304 pH/EC/TDS Combo Tester

There will be no need to keep swapping between meters for your routine measurements with this floating, waterproof combination tester. It has an easy-to-read LCD 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 (β).

Features

• Waterproof – designed to float if accidentally dropped in water
• Automatic Temperature Compensation – All readings are compensated for variations in temperature and temperature is displayed along with the pH reading.
• Stability indicator – Meter displays a tag that will disappear when the reading has achieved stability
• Hold button – Freezes reading on the display to allow recording of measurement
• BEPS (Battery Error Prevention System) – Meter will automatically shut off if there is not enough power to get an accurate measurement
• Battery % level at start up
• Low Battery Indicator
• Automatic Shut-Off – The meter can be set to automatically turn off after 8 minutes or 60 minutes to conserve battery life in the event that the meter is left on. The auto off feature can be disabled.

 

High accuracy EC/TDS Graphite Probe

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

 

Replaceable pH electrode cartridge

The combo features an easy to replace pH electrode. The sturdy, snap-in connector means there are no pins which could bend or break.

 

Protective Cap

The protective cap features an internal cup that can be filled with storage solution to keep the pH sensor moist.

 

Calibrate right in the sachets

Calibration can be performed directly into the solution sachets.
