HI98107 & HI98108 pHep Line of Handheld Waterproof pH Meters

Hanna Instruments Waterproof Handheld pH Meters HI98107 and HI98108 https://shorturl.at/acS57 https://shorturl.at/yGNX3 In 1986 The pHep family of pocket meters revolutionized pH measurement by providing millions of users access to an affordable and easy-to-use pH meter. In this video, we will introduce you to our latest generation of testers. Our two most popular meters in the pHep family have been redesigned. They are: HI98107 HI98108 Both meters operate in the same fashion with the only difference being the resolution, The pHep meters are designed with accuracy and simplicity in mind. Starting with a slim ergonomic design that fits comfortably in your hand and a high contrast large display that is easy to read. The daily operation of the meter has been simplified to just two buttons. One is for turning the meter on and off while the other is used to enter the calibration mode. There is a third button in the battery compartment that allows the user to choose the displayed temperature unit and adjust the automatic shut-off time. Looking at the sensor portion of the meter the pH electrode, temperature probe and cloth reference junction can be seen. The cloth reference junction is extractable when there is a stability issue with the readings the junction is pulled 1/8” from the meter to expose a fresh surface. The extractable cloth junction offers a great benefit in extending the life of the pH electrode. The exposed temperature probe of the pHeps provides for a rapid temperature measurement to compensate for any temperature variations in the calibration buffers or samples being measured. This is absolutely necessary to achieve a high accuracy reading, especially with samples at the extremes of temperature and pH. To operate the meters simply press the left on/off button to turn on. All the LCD segments are displayed then the battery % level is displayed, notifying the user of the remaining battery life. In operation mode, the following can be seen: Instability indicator that disappears when a steady reading is obtained pH reading Temperature readout If calibrated, calibration tags showing which pH points have been calibrated To calibrate the meter press the ‘CAL’ button while the meter is on to enter calibration mode. For two-point calibration, the meter will prompt for the pH 7.01 buffer. Once the buffer is automatically recognized the buffer will be updated REC will be displayed and the meter will then display pH 4.01 For single-point calibration, press the CAL Key to exit SAVE is displayed and the meter returns to measurement mode. If needed, the default settings for the temperature unit displayed and automatic shut-off can be adjusted. With the meter turned on and the battery cover removed a microswitch inside the battery compartment is pressed to enter the setup mode. The first setting displayed is the selection for the temperature unit. At default the TEMP measurement unit is °C. Pressing the CAL button changes the displayed unit to oF. Pressing the CAL button again changes it back to °C. Pressing the ON/ OFF button moves to the next setup option, which is for automatic shut-off. The default setting is for 8 minutes. Pressing the CAL button cycles through to 60 minutes then disabled and finally back to 8 minutes. Pressing the ON/ OFF button again exits the setup mode and the meter is back in measurement mode.
