Details
HI12883 Multiparameter Probe
The HI12883 multiparameter probe includes pH, EC/TDS, and temperature measurement. A solid-state pre-amplifier is integrated into the probe to protect against interference from transient electrical noise.
- Amperometric conductivity probe
- Built-in temperature sensor
- Easy-to-clean
- The sensor is easy to clean and maintain by design
- pH sensor with extendable cloth junction
- The HI12883 multiparameter probe features a cloth junction that can be pulled longer, effectively increasing the life of the probe
Features at-a-glance
-
3 sensors in a single probe
pH electrode - Preamplified for resistance to electrical noise including that generated by pumps and ballast
EC/TDS sensor - amperometric two pole design
Temperature - NTC sensor for accurate temperature measurement and compensation-
Waterproof
Designed to withstand the humidity of a growing environment-
Wide pH Range
pH range is from 0.00 to 14.00 pH-
Selectable EC to TDS conversion factor
Choice of either a 0.5 or 0.7 conversion factor0.5 (500 CF) conversion factor is for an EC reading of 10 mS/cm = 5 ppt0.7 (700 CF) conversion factor is for an EC reading of 10 mS/cm = 7 ppt- Automatic Temperature Compensation
All readings are compensated for variations in temperatureTemperature displayed in oC or oF along with pH, EC or TDS reading-
Stability indicator
Meter displays a clock tag that will disappear when the reading has achieved stability-
HOLD button
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
User selectable automatic shut-off ff to conserve battery life. Options are after 8 minutes, 60 minutes , or disabled.
