The HI99141 is a waterproof, portable pH and temperature meter specifically designed for boilers and cooling towers. The HI72911D pre-amplified double junction pH probe features a flat tip sensor that is easy to clean and prevents solids in solutions from collecting on the sensor. The titanium body of the HI72911D functions as a potential matching pin for increased stability of readings and extended sensor life.
  • Automatic Temperature Compensation
  • Automatic Two-Point Calibration
  • Waterproof

Details

The HI99141 meter features a large multi level LCD screen which displays both pH and temperature readings simultaneously with 0.01 pH resolution and an accuracy of ±0.05 pH. The LCD screen also has indicators for calibration status and stability, as well as on-screen tutorial messages. The HI99141 has many advanced features that are found in more expensive portable instrumentation including automatic calibration, buffer recognition,and temperature compensation. The battery percent level is displayed at start up alerting the user to the remaining battery power that is available.

The HI99141 is supplied with the amplified titanium body pH/temperature electrode. The titanium body is resistant to many aggressive chemicals and extremely durable.The titanium body acts as a matching pin for the flat tip pH electrode. A matching pin is a differential measurement technique used to eliminate electrical noise in a pH measurement system. The matching pin coupled with a pre-amplifier provides for an increased response time in pH measurement and extends the electrode life.

The HI72911D also features a large annular polytetrafluoroethylene (PTFE) junction. This large junction is resistant to chemicals but has a large surface area allowing for maximum diffusion of ions from the inside of the reference electrode into the sample resulting in a fast, stable reading. The flat tip pH electrode with a PTFE junction in a titanium body make the HI72911D ideal for the water treatment industry.
