This document is an instruction manual that provides information on the correct use and versatility of the Hanna Instruments Dissolved Oxygen and Temperature Meter HI 9146.
The Hanna Instruments HI 9146 is a state-of-the-art, heavy-duty dissolved oxygen (DO) meter designed for laboratory results and accuracy under harsh industrial conditions. It features a built-in thermistor for temperature measurements and automatic compensation for temperature, salinity, and altitude. The instrument includes diagnostic features such as the Auto Endpoint function to freeze stable readings and a Battery Error Preventing System (BEPS) to warn of low battery conditions.
The manual details the preliminary examination, functional descriptions of the probe and meter, and operational guides including probe polarization, salinity and altitude compensation, and DO measurements. It also covers Good Laboratory Practice (GLP), setup procedures, battery replacement, probe and membrane maintenance, troubleshooting, and warranty information.
| Battery Type | 3 x 1.5V AAA |
|---|---|
| Warranty Period | two years |
The instrument is guaranteed for two years against defects in workmanship and materials.
Electrodes and probes are guaranteed for six months.
The Battery Error Preventing System (BEPS) detects weak batteries, disables the backlight, and the meter automatically switches off if the batteries are too weak to support proper function.
Allow approximately one minute for the reading to stabilize after immersing the probe in the sample.
