Description
Características
The HI9125 is a rugged, portable pH and mV meter designed to provide accuracy in adverse industrial and environmental conditions. The meter offers a variety of features including automatic 1- or 2-point calibration, automatic temperature compensation, a two-level LCD display, on-screen instructions, and a battery error prevention system.
The HI9125 meter has selectable pH and mV units. MV mode is used with an optional ORP electrode for determining oxidation limits or reducing a solution. Hanna offers a variety of ORP electrodes in different materials, from glass to PEI plastic body probes.
Use the universal BNC probe input for pH and ORP electrodes. The universal BNC connector allows the user to select from a wide variety of electrodes based on their particular application. A separate RCA connector is used for a thermistor temperature probe. The temperature probe provides high measurement accuracy of ± 0.4 ° C for precise temperature compensation.
Funcionamiento
One- or two-point calibration: Automatic calibration can be performed in 1 or 2 points using the 5 pre-programmed solutions (pH 4.01, 6.86, 7.01, 9.18 and 10.01).
On-screen instructions – Clear, easy-to-use on-screen instructions to guide you through all the steps to calibrate and take measurements.
Durable and Strong Plastic Body pH Electrode – This pH meter is supplied with the PEI HI1230B Body Electrode, gel-filled double junction pH electrode. The PEI body offers excellent chemical resistance to many aggressive chemicals. The double junction design meant that contamination of the Ag / AgCl electrolyte resulted in a blocked junction. Since the HI1230B is gel filled, it does not require maintenance of an electrolyte solution.
Temperature Compensation – The HI9125 meter offers automatic or manual temperature compensation for pH measurements in a wide range of -20.0 to 120.0 ° C.
MV Mode: The HI9125 has an mV mode that can be used with a wide variety of ORP electrodes to monitor the effects of oxidation reduction.
Measurement recall: This equipment has a “MEM” button to store a reading. The reading can be retrieved at any time by pressing the “MR” memory recall button.
Auto Power Off – Has an adjustable auto power off function. The meter can be configured to avoid 20 minutes of inactivity and prevent battery waste. Or, you can disable this option so that the user has the user.
Battery Error Prevention System (BEPS) – The Battery Error Prevention System is detected when the batteries become too weak to guarantee connections.
The HI9125 meter is supplied complete with:
- pH electrode, double junction, gel interior (HI1230B).
- Stainless steel temperature probe with 1-meter cable (HI7662).
- Buffer solutions of pH 4.01 and pH 7.01, 20 ml sachets (HI70004 and HI70007).
- 100 ml plastic cup.
- 4 1.2 AAA rechargeable batteries (inside the equipment).
- Inductive charger with transformer (HI710044).
- Manual.
- Robust carrying case.
