Bluetooth Water Hardness Tester - Wireless Pen Type Hardness Meter - 0.05-200 mmol/L, ±1% F.S.

The Master Science Bluetooth Water Hardness Tester is a pen-shaped probe with a solid-state sensor that sends its readings wirelessly to an Android smartphone or tablet. The mobile device acts as the display, memory and control panel, while the tester itself stays small enough for a pocket.

Hardness is measured from 0.05 to 200 mmol/L and can be shown in °dH, °e, °fH, gpg, mg/L or mmol/L. The Master Science Bluetooth Water Hardness Tester is calibrated on 2 to 5 points, and its setup menu holds 12 options including alarms, timed readings and password protection.

Product Features

Measurement

• Bluetooth water hardness tester supplied with a solid-state sensor
• 2 to 5 point calibration with five selectable concentration points
• Selectable units: German degree (°dH), English degree (°e), French degree (°fH), gpg, mg/L and mmol/L
• Manual temperature compensation removes error caused by temperature deviation
• Auto-Read function senses and locks the measurement endpoint

Data and Control

• Timed interval readings send measurement data to memory or a printer
• Limit alarm alerts when a reading goes beyond the specified range
• Calibration due alarm prompts regular calibration
• Calibration report shows date, time, calibration points and slopes
• Password protection prevents unauthorised calibration and settings
• Multiparameter measurement: Bluetooth conductivity and dissolved oxygen testers can connect to the device at the same time
• Reset function restores all settings to factory defaults

Applications

The Master Science Bluetooth Water Hardness Tester is practical for hardness checks in:

• Drinking water and household water surveys
• Water softener and treatment system checks
• Boiler and cooling water monitoring
• Field sampling and teaching work

Common Problems This Tester Solves

Portable hardness testing usually means compromises; this design removes several of them.

• Small meter screens are hard to read:: results appear on a phone or tablet display.
• Out-of-range values are missed:: the limit alarm flags them immediately.
• Anyone can alter calibration:: a 6-digit password locks calibration and settings.
• Carrying several meters to site:: conductivity and dissolved oxygen Bluetooth testers can share the same device.
