The HI98130 is a highly accurate, waterproof combo ph ec tester that can also measure EC/TDS in the high range (0.00 to 20.00 mS/cm EC/ 0.00 to 10.00 ppt TDS) and temperature. This floating, waterproof combination tester has an easy to read, LCD and an automatic shut-off. In addition, pH and EC/TDS readings are automatically temperature compensated (ATC) to prevent temperature-related variations in your measurements. For EC/TDS 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 HI98130 pH and conductivity 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/TDS Graphite 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.
- 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
3 sensors in a single meter
- pH electrode with extractable junction
- Amperometric EC/TDS sensor
- Exposed temperature probe for faster EC/TDS 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 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 in oC or oF along with pH, EC or TDS reading
