HANNA HI 981504 pH/TDS/Temperature Monitor

HANNA HI 981504 pH/TDS/Temperature Monitor

• Simultaneous display of pH, TDS and temperature
• Continuous measurements
• Measure in °C or °F
• Three, backlit displays

Set-up is simple. Install the HI 981504 near the sample to be tested, plug the indicator in and immerse the probes. pH, TDS and temperature measurements will be simultaneously displayed on three backlit LCDs.
Users can easily select the temperature unit (°C or °F) on the back panel.

The HI 1286 gel-filled pH electrode is provided with a waterproof sleeve to protect the BNC connector. The unique design of the electrode provides longer life in aggressive solutions. The HI 7634 TDS probe is easy to clean and requires little maintenance. Measurements are accurate and the meter can be calibrated at one or two points for pH and at a single point for TDS. Temperature is factory calibrated.
