Economical – The Checker Plus is a full-featured pH tester at a price that anyone that needs to measure pH can afford.

Large LCD - Enhanced LCD that displays reading, stability indicator, low battery indicator and calibration tags.

Replaceable pH Electrode - The HI1271 supplied gel filled pH electrode tapers to an 8 mm diameter at the sensing end. This narrow electrode easily fits into test tubes, vials, and other containers with a small opening.

Automatic Calibration - The Checker Plus is calibrated automatically to one or two points. The calibration buffers are automatically recognized and after calibration the buffer values used are shown on the display as a tag.

Stability Indicator – An hourglass indicator is displayed on the LCD until a stable reading is obtained. Once a reading stabilized the indicator disappears and a reading can be recorded.

Automatic Shut-Off – The meter can be set to automatically turn off after 8 minutes or 60 minutes to conserve battery life in the event that the meter is left on. The auto off feature can be disabled.

Long Battery Life - The Checker Plus has an exceptional long battery life of approximately 1000 hours. When the battery power is running low a low battery indicator is displayed.

Slim, Ergonomic Design - With rounded edges and a case that is only 17 mm (0.7”) thick, the HI98107 is thin and fits comfortably in the hand or pocket.

Large Multi-level LCD - The LCD is 29 mm (1.125”) x 20 mm (0.81”) allowing the user to easily read both the pH and temperature simultaneously.

Integrated Temperature Sensor - Built in temperature sensor allows for temperature compensated measurements. Temperature can be displayed in either °C or °F.

Automatic Calibration - Automatic calibration to one or two points using standard buffers (pH 4.01, 7.01 and 10.01).

Stability Indicator - A clock tag stability indicator will disappear to alert the user when the reading is stable.

Automatic Shut-off - User-selectable time until meter shuts off to conserve battery life. Options are 8 min, 60 min or disabled.

Low Battery Indicator - Low battery indicator that is displayed when less than 10% battery life is remaining.

Battery % Level at Startup - At start-up, all the LCD segments are displayed for 1 second, then the percent indication of the remaining battery life is displayed.

pHep®4 features automatic one or two-point calibration and automatic temperature compensation.

The large multi level LCD display shows both pH and temperature readings simultaneously, while a stability indicator is displayed to alert the user when a stable reading has been obtained.

The pHep®4 tester also features a replaceable pH probe that has a unique extendable cloth junction to clear any clogging that occurs.

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

Auto-off - Meter automatically shuts off after 8 minutes of non-use to maximize battery life

Hanna Instruments is proud to introduce the world’s most innovative pH meter : edge ®.Edge is a single meter that can measure pH, Conductivity, and Dissolved Oxygen and is incredibly easy to use. We put a lot of thought into edge’s ease of use.

Large easy to read LCD, Capacitive touch, Clear full text readout.

Digital Electrode - edge electrodes are highly advanced, featuring a built-in microchip that stores calibration information that is automatically retrieved by edge once the electrode is plugged in.

Wall mount using the wall mount cradle (included), edge can be placed on a wall, leaving zero footprint on the benchtop space.

Cradle and Electrode Holder - edge is equipped with a benchtop cradle with an adjustable swivel electrode holder to charge and hold the edge securely in place at the optimium viewing angle.

HI2020 pH kit includes : HI11310 Glass body, refillable pH electrode with temperature sensor, 2 sachets of pH 4 buffer solutions, 2 sachets of pH 7 buffer solutions, 2 sachets of pH 10 buffer solutions, Electrode cleaning solutions and Quality certificate.

This meter will give you accurate readings of the pH in your soil and with the press of a button it will let you know how moist your soil is to help prevent you from over watering.

An excellent gardening accessory for those gardeners that tend to over water and those that want to keep a close eye on their pH level.

HANNA® buffer solutions are prepared according to precise formulas and are standardized with a pH meter calibrated according to the NIST standards.

All HANNA buffer solutions show batch number, expiration date and the correlation table between pH and temperature.

To ensure an optimum response time, the glass sensor tip and the reference junction of the pH electrode should be kept moist and not be allowed to dry out when not in use.

Placing the electrode in a small glass filled with storage solution or replacing the solution in the protective cap is a suitable way to store the electrode.

The HI 70300L should also be used to rehydrate the electrode after a cleaning procedure by soaking for at least one hour before taking measurements.

Never store pH or ORP electrodes in distilled or deionized water. Doing so will shorten the life of the sensor.

Air tight bottle with tamper-proof seal - Ensures quality and freshness of solution

Hanna storage solutions are specially formulated to have an expiration of 5 years from manufacture for an unopened bottle.
