Description
With a 0.01 pH resolution and an accuracy of 0.02 pH, the HI991001 meter’s wide multi-level LCD screen simultaneously shows pH and temperature measurements. Additionally, the LCD panel offers on-screen instructional instructions and indicators for calibration stability and status. Numerous cutting-edge capabilities, such as automatic calibration, buffer identification, and temperature adjustment, are present in the HI991001, which are often only seen in more expensive portable instrumentation. At startup, the battery percentage level is shown to inform the user of the remaining battery power.
pH Electrode with Quick Connect DIN Connector, Model No. HI12963
The titanium body pH/temperature electrode is included with the HI991001. The strong chemicals employed in chemical manufacture and plating are all resistant to the titanium body. Together with the internal amplifier, the titanium body serves as a matching pin to lessen the impact of electrical noise on the high impedance pH measurement. Rectors, motors, and ballasts are a few examples of electrical noise generators.
An extractable cloth connector is another feature of the HI12963 pH electrode. The HI12963’s extractable cloth junction makes it possible to replace the junction. By just pulling on the junction, you can disclose a new part by removing 1/8″ of the connection. The pH electrode’s lifespan will be extended after any blockage that was present has been cleared and the reaction time has returned to normal.
- Titanium body that is resistant to harsh chemicals
- Pre-amplified and matching pin for resistance to electrical noise
- Extractable cloth junction to clear any clogging
- Built-in temperature sensor for automatic temperature compensated readings
Features at-a-glance
Waterproof
- Designed to float if accidentally dropped in a tank
Expanded pH Range
- pH range is from -2.00 to 16.00 pH
Automatic Two-Point Calibration
- One or two-point calibration is automatic to two selectable buffer sets (4.01, 7.01 and 10.01 or NIST 4.01, 6.86, and 9.18).
Automatic Temperature Compensation
- All readings are compensated for variations in temperature
- Temperature displayed in °C or °F along with pH 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
- Meter automatically shuts off after 8 minutes of non-use to maximize battery life
