HI 98107 pHep^® pH Tester

PHEP HANNA PH tester

Renewable junction
Easy 1 or two points manual calibration
700 hour battery life
Simple to use
Economical

The pHep^® revolutionized the pH industry by providing non-technical personnel with a simple, inexpensive solution to accurate pH measurement.

HI 98107 is used by millions of people around the world to monitor pH in laboratories and industrial applications as well as in agriculture, fish farming, food manufacturing and quality control, swimming pools and the printing industry.

With a renewable cloth junction, the pHep^® has an extended life over typical pH testers. A normal junction clogs with use over time and a typical tester would normally have to be thrown away once the junction is too contaminated. HI 98107’s junction is 2 cm long and when dirty, can be pulled out to expose a fresh section to effectively renew the pHep’s life.

Calibration is performed manually at 1 or two points with a trimmer located on the side of the tester.

With a battery life of 700 hours of continuous use, the pHep^® will provide years of testing before the batteries need to be replaced.

Order Information:
HI 98107 (pHep®) is supplied with protective cap, calibration screwdriver, batteries and instructions.

HI 2223 Calibration Check™ pH/ORP/Temperature Benchtop Meter
with extended pH range

pH Calibration Check™
On-screen electrode condition and response time
Up to five point calibration with seven standard buffers
Diagnostic alerts through icons
Automatic Temperature Compensation
Log up to 500 samples
GLP features
PC interface via US

A properly manufactured and maintained pH electrode will retain its measuring integrity for a long time. As a result of many factors such as age, poor maintenance or improper handling, any electrode in time will lose its integrity.

The most common cause for pH measurement inaccuracies is an unclean or improperly cleaned electrode. This is very important to note, because during calibration, the instrument assumes that the electrode is clean and that the standardization curve created during the calibration process will remain a valid reference until the next calibration.

A dirty electrode or wrong calibration approach can contribute to buffer solution contamination. A contaminated buffer solution can present a major problem during calibration due to the fact that it is considered the only reference.

The HI 2223 is a pH benchtop meter featuring our exclusive Calibration Check™ diagnostics for both pH?electrodes and buffer solutions during calibration. This instrument compares the characteristics of the pH electrode from one calibration to the next. In the case of large variances in the electrode condition, it alerts the user that the electrode needs to be properly cleaned prior to calibration and measuring.

The second feature is to detect if the calibration buffer solution is contaminated. After calibration, the probe condition is evaluated and an indicator is displayed informing the user of the overall pH electrode status.

This meter can measure using ORP electrodes (pH channel input), due to it’s capability to measure mV with a resolution up to 0.1 mV.

HI 2223 also features five point calibration with seven standard buffers, Automatic Temperature Compensation and GLP capabilities that allow for the storage and retrieval of all data regarding pH. With a built-in logging function, measurements are stored in non volatile memory and can be transferred to a PC through the USB port. Users can manually log up to 200 records and interval log up to 500 records.

The BL 931700 mini pH controller has been designed for easy, affordable installation in tight spaces to perform simple yet effective process control. Thanks to its compact size, the BL 931700 mini pH controller can be installed right next to tanks or vats.

This versatile controller is ideal for a wide variety of applications, such as textiles, papers, photographic solutions, plating baths, chemicals and water treatment.This

BL 931700 is provided with a selectable set point for acid or basic dosage.

Measurements are directly taken from a pH electrode in the range from 0 to 14 with a 0.01 pH resolution. Accuracy is ensured by two point calibration, performed manually through trimmers on the front panel.

Users can choose automatic or manual dosing mode with a switch on the front panel. Manual control is particularly useful during maintenance operations, because
it permits operators to enable or disable the dosing relay according to need. The overtime control system advises users when the relay is active for too long, helping to prevent overdosing.

In addition, this model features a 4-20 mA analog output for recorder connection.
