HI98129 Combo pH/EC/TDS Tester and Related Products
The HI98129 is an easy-to-use and accurate waterproof pH, conductivity, TDS (ppm) tester. It measures pH, EC in the low range (0 to 3999 µS/cm), TDS (0 to 2000 ppm), and temperature. This floating, waterproof combination pocket tester has an easy to read, LCD and an automatic shut-off. All pH, EC, and TDS (ppm) readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC and TDS (ppm) readings, the EC/TDS conversion factor (CONV) is selectable by the user, as well as the temperature compensation coefficient β (BETA).
REPLACEABLE PH ELECTRODE CARTRIDGE
The HI98129 tester features an easy to replace pH electrode cartridge with an extendable cloth junction. The extendable cloth junction helps increase electrode life and the replaceable pH cartridge means that this tester does not need to be thrown away when the pH sensor is exhausted. Also, the sturdy, snap-in connector means there are no pins to bend or break!
HIGH ACCURACY EC AND TDS (PPM) TESTER PROBE
The graphite conductivity probe provides greater accuracy because it cannot be contaminated by salt deposits in the solution. The exposed temperature sensor provides fast response times and guarantees highly accurate temperature compensated readings.
·3 sensors in a single tester
pH electrode with extractable junction
Amperometric EC/TDS sensor
Exposed temperature probe for faster EC and TDS (ppm) readings
Designed to float if accidently dropped in sample
·Wide pH Range
pH range is from 0.00 to 14.00 pH
·Selectable EC to TDS (ppm) conversion factor
Choice of either a 0.45 or 1.0 conversion factor
·Automatic Temperature Compensation
All readings are compensated for variations in temperature
Temperature displayed inoC oroF along with pH, EC or TDS reading
Meter displays a clock tag that will disappear when the reading has achieved stability
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 startup
·Low Battery Indicator
When the level is below 5%, the battery symbol on the LCD blinks to indicate a low battery condition.
Auto-off feature automatically shuts off meter after 8 minutes of non-use to maximize battery life
