Add Quotation


The HI991001 is a compact, waterproof, portable pH/temperature meter that is supplied complete including a rugged carrying case and a unique titanium body pH electrode that has a built in temperature sensor. The meter features a large LCD that displays for easy viewing of the pH, temperature and status indicators. The operation of the meter is simplified to two buttons. The HI991001 has an exceptional long battery life of 1200 hours of continuous use.

Details

The HI991001 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 HI991001 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 supplied HI1296D is a titanium body, amplified pH electrode with a built-in temperature sensor. The titanium body is resistant to many chemicals including those found in plating shops and chemical manufacturing. The matching pin along with the amplifier prevents interference from humidity and electrical noise from common sources including from motors, ballasts, or rectifiers.
