Hanna Instruments

The low range Combo^® pH, EC, TDS (ppm) and temperature meter (4HA98129) is one of Hanna's most popular meters. The waterproof design, simple operation, and replaceable electrode mean that you can rely on this meter for years. The 4HA98129 is designed for low range use (0 to 3999 µ/cm or 0-2000 ppm). Choose the Hanna 4HA98130 model for high range model.

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!

Accurate, Waterproof. No more switching between meters for routine measurements with the 4HA98130 pH and Conductivity tester. A highly accurate, waterproof combo pH EC tester that can measure EC / TDS in the range (0.00 to 20.00 µS/cm EC/ 0.00 to 10.00 ppt TDS) and temperature.
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. Replaceable pH Electrode Cartridge (4HA73127) extends the life of your tester.

The 4HA9813-61 is a portable, water resistant meter designed for measuring the pH / EC / TDS and temperature when paired with its respective probe, the 4HA1285-61. The meter is easy to use, with dedicated keys for measurement modes that are clearly displayed on the LCD, and knobs for 1-point calibration of pH and EC. On-screen tutorial messages guide the user through calibration and measurement.

Edge^® Multiparameter pH Meter delivers precision while offering simplicity and versatility in a sleek design. The electronic pH meter will automatically recognize each digital electrode, providing sensor type, calibration data and serial number. Advanced pH electrode diagnostics ensure worry-free measurements. Usse your mulitparameter pH meter as a portable, benchtop meter, or mount it on a wall to save space.

Edge^® Dedicated pH /ORP Meter is seriously thin and light with lab grade functionality packed into a tablet design. With simple operation and advanced features, edge pH easily outperforms all other portables and bench tops in its class.

The 4HA6221 Advanced pH/ORP Benchtop Meter is a streamlined benchtop meter with a large touch screen display, comprised of housing and an integrated pH / ORP measurement module. Compact and easy to operate, the benchtop meter is delivered with Hanna's 4HA1131B double junction combination pH electrode, together with 4HA7662-TW temperature probe.

Measure pH/MV (pH) or mV / Rel.mV (ORP) with temperature. Features 5-point pH Calibration capacity with automatic recognition for standard or custom buffers.

The 4HA11310 is a combination, glass, refillable pH electrode with a built-in temperature sensor. This probe features a 3.5 mm connector designed exclusively to be used with Hanna Instruments Edge^® Tablet Meters.

The built-in microchip stores sensor type, serial number and calibration information including date, time, offset, slope, probe condition and buffers used. This information is automatically retrieved by Edge^® once the electrode is plugged in. The ability to transfer information allows for hot-swapping of probes without having to recalibrate. All pH measurements are performed within the electrode and transferred digitally to the meter. This overcomes any noise issues associated with the traditional high impedance analog measuring system. Electrical noise can be generated from a built-in temperature sensor and while working in a humid environment.

Ideal for general laboratory use, the 4HA1131B is a glass-bodied combination pH electrode with a BNC connector for a quick and easy connection to any BNC pH meter. With a double junction design and the ability to change out contaminated electrolyte, this economical pH electrode ensures great results.

Gel Filled PEI Body pH Electrode with BNC Connector (4HA6XXX meters) The 4HA1230B pH electrode has a PEI body, double junction, and a BNC connector. The spherical pH sensing portion is made with general purpose glass, suitable for most pH measurements, and is protected by an extension of the durable PEI body.

The 4HA9813-61 and 4HA9810-61 are supplied with the 4HA1285-61 pH/EC/TDS/temperature probe with CAL Check^.™ The pH, EC, TDS, and temperature sensor are housed in a single body that connects to the meter with a DIN connector.

Hanna Instruments offers a wide variety of electrodes that are designed for many different applications. The sensing material, body material, and connection type used are just some of the design considerations. 4HA1285-6

The 4HA1271 is the Spare pH Electrode for 4HA98100 / 4HA98103 Checker^® pH meters. Replacing the pH electrode is both quick and easy. Simply unscrew the old probe to be replaced and screw on the new one. The 4HA1271 is a single junction pH electrode that has a slim 8 mm polypropylene body that easily fits into test tube and other small sized vessels.

The 4HA73127 spare pH sensor makes electrode replacement quick and easy. The spare pH sensor is designed as an easy-fit cartridge that locks into place, featuring two o-rings to maintain a watertight seal. With no pins to line up or that can break, this sensor is ideal for quick replacements.

4HA73128 is a replacement tool for electrode removal on select Hanna waterproof testers including models - 4HA98120, 4HA98121, 4HA98127, 4HA98128, 4HA98130, 4HA98311, 4HA98312
