Hanna Instruments HI991001 Waterproof Portable pH/Temperature Meter

The HI991001 is a small, water-resistant, handheld pH/temperature meter that comes with everything you need, including a durable carrying case and a special titanium pH electrode with an integrated temperature sensor. For convenient viewing of the pH, temperature, and status indications, the meter has a sizable, dual-level LCD display. The meter’s controls are reduced to two buttons. The HI991001 has a battery life of 1400 hours, which is exceptionally lengthy.

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.

HI1296D

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.

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
