HANNA COMBO METER: PH / CONDUCTIVITY / TDS / TEMPERATURE

The new waterproof HI98129 & HI98130 Combo testers from Hanna are designed for high accuracy pH, EC/TDS and temperature measurements. No more switching meters to measure the pH and then the EC or TDS of a solution. At startup, Combo performs a self check then displays the remaining battery level to assure proper working condition. These testers also have a stability indicator and hold feature to prompt the user when to take the reading & freeze the display for easy and accurate recording. Calibration and temperature compensation is automatic, while the EC / TDS conversion factor and temperature coefficient factor () are user adjustable for application specific measurements. For calibration in pH, the user may choose between standard or N.I.S.T. buffer sets. The combo has a replaceable pH electrode cartridge with an extendable cloth junction as well as an EC/TDS graphite electrode, which resists contamination by salts and other substances that come in contact with the electrode. These new pH / EC / TDS / Temperature meters have a stainless steel temperature probe for faster and more precise temperature measurement. Fast, efficient, accurate and portable, the Combo pH, EC/TDS and temperature tester meets the requirements of your routine multi-measurements.

Choose your Combo according to the proper EC / TDS ranges for your application:

orp meter
HANNA ORP/TEMP METER:

The HI98120 is a waterproof ORP and temperature handheld meter. The housing of this tester is completely sealed to protect against the intrusion of water and is also designed to float if accidentally dropped into a body of water. The HI73120 replaceable ORP electrode is a cartridge design with the stainless steel round connector. With this type of design there are no pins that can bend or break during replacement. The ORP electrode also has an extendable cloth junction. This type of junction allows for the renewal of the junction by simply pulling out 3 mm (1/8") to clear any clogging which improves measurement response time and stability. The exposed stainless steel temperature probe on this meter facilitates a faster, accurate temperature measurement.

Features at-a-glance:
Waterproof
- IP67 rated
- Protects the internal electronics of the meter from an ingress of water in the event that the meter is dropped into a tank or a body of water.
Stability indicator
- HI98120 features a stability indicator tag on the LCD that will disappear once the reading stabilizes.
Replaceable electrode
- An electrode last approximately one to two years. It is possible to replace just the electrode and not have to buy a completely new meter.
- The HI73120 ORP electrode is a simple cartridge design allows the sensor to be easily replaced whether in the lab or in the field.
HOLD feature
- Allows the reading to be frozen so that the reading can be documented.
Auto-shut off
- The meter automatically turns itself off after 8 minutes of use in order to conserve battery life in the event the meter is accidently left on.
Battery % level
- When the meter is turned on the battery % level is displayed as a percentage.

ORP TEST SOLUTIONS

Quality ORP test solution made from reagent grade chemicals and used to test platinum and gold ORP electrodes. Hanna test solutions have the lot number and expiration date clearly marked on the label and are air tight with a tamper-proof seal to ensure the quality of the solution. - Prepared with reagent grade chemicals - Allows for a quick check of your ORP electrode - Air-tight seal to ensure the quality of the solution

These ORP test solutions are designed for testing the performance of ORP electrodes. This solution allows users to quickly see if their electrodes are reading correctly. Using this as a diagnostic tool, users can then decide if the ORP electrode needs to be cleaned and conditioned. The test solutions are produced using reagent grade chemicals in a temperature controlled environment.

HI7021L: When the ORP electrode is placed in the test solution the reading obtained should be within +/- 20 mV of the 240 mV @ 25°C value.
HI7022L: When the ORP electrode is placed in the test solution the reading obtained should be within +/- 10 mV of the 470 mV @ 25°C value.
