Hanna HI-98129 Digital pH/Conductivity/TDS Meter 0 - 14.00 pH HI98129 in Lucknow
Hanna HI98129, pH/EC/TDS/ Temperature Meter (Combo Pack)
HI 98129 and HI 98130 are waterproof pH, EC/TDS and temperature meters. The housing has been completely sealed against humidity and designed to float. All pH and EC/TDS readings are automatically temperature compensated (ATC), and temperature values can be displayed in °C or °F units.
For EC/TDS readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient ? (BETA).
The meters can be calibrated at one or two points for pH (with auto-buffer recognition and against five memorized buffer values), and at one point for EC/ TDS.
Measurements are highly accurate with a unique stability indicator right on the LCD.
A low battery symbol warns the user when the batteries are to be replaced. In addition the Battery Error Prevention System (BEPS) avoids erroneous reading caused by low voltage level by turning the meter off. The HI 73127 pH electrode, supplied with the meters, is interchangeable and can be easily replaced by the user.
The stainless steel encapsulated temperature sensor facilitates faster and more accurate temperature measurement and compensation.
