pH meter HANNA HI 9124 (portable)
Portable waterproof pH meter Hanna HI 9124 with electrode HI 1230V The Hanna HI9124 is a rugged, portable pH and mV meter designed to provide accurate and accurate measurements in harsh environmental and industrial environments. The device has a large number of modern functions, including automatic calibration at 1 or 2 points, automatic temperature compensation, backlit LCD display, on-screen instructions, battery error prevention system. To connect pH electrodes, the HI9124 device uses a universal BNC connector. The universal BNC connector allows the user to select from a wide range of electrodes depending on their specific application. A separate RCA connector is used to connect a thermistor-based temperature sensor. To ensure accurate temperature compensation, the temperature sensor provides high measurement accuracy of ±0.4 °C. Advantages of Hanna HI 9124 One or Two Point Calibration - Automatic calibration can be performed on one or two points using 5 standard buffers (pH 4.01, 6.86, 7.01, 9.18 and 10.01). On-Screen Instructions – Clear, easy-to-follow on-screen instructions guide you through every calibration and measurement step. Durable pH Electrode in Plastic Housing - The HI9124 comes complete with the gel-filled pH electrode HI1230B in a polyetherimide plastic housing and dual diaphragm. The polyetherimide housing offers excellent chemical resistance to many harsh chemicals. The dual diaphragm design helps minimize contamination of the internal reference cell, which can cause Ag/AgCl electrolyte precipitation and diaphragm clogging. HI1230B electrodes are gel-filled and do not require replenishment of electrolyte solution to maintain functionality. Temperature Compensation - The HI9124 provides users with a choice of automatic and manual temperature compensation for pH measurements over a wide range of −20.0 to 120.0 °C. Calling a saved value - the HI9124 device is equipped with a “MEM” button for saving the measurement result. The saved result can be recalled at any time by pressing the “MR” memory recall button. Automatic Shutdown - The HI9124 has an adjustable automatic shutdown feature. To prevent accidental battery discharge, the device can be programmed to automatically turn off after 20 minutes. This feature can be disabled; in this case, the user must turn off the device using the power button. Battery Error Prevention System (BEPS) - The system detects when the batteries become too low to provide reliable readings. Manba: https://www.nv-lab.ru/catalog_info.php?ID=2672
