Water Quality Monitoring

The Bluetooth Pen Meter (DORP1+) is a pocket-sized, single-parameter pen tester measuring Oxidation-Reduction Potential (ORP) from -1000.0 to +1000.0 millivolts with accuracy of ±0.1 percent of full scale ±1 digit and resolution of 0.1 or 1 millivolts, featuring replaceable combined electrode design (DORP1-S), multi-color backlit LCD display with reading stability indicator and automatic data lock, IP67 dustproof and waterproof rating, 0 to 60 degrees Celsius temperature measurement with ±0.2 degrees Celsius accuracy, 1-point automatic calibration with 222 millivolt ORP standard, support for CH, USA, and NIST standard buffer solutions, low battery indicator, user-configurable automatic shut-off and backlight duration, power-on self-diagnosis, and Bluetooth connectivity to a mobile application for two-way control, unlimited data storage, graphical display modes (chart, curve, dial, and normal), graphic navigation operation guides, calibration reminders, measurement object identification management, timed storage, and high and low value warning settings—ideal for water quality testing in clinical, pharmaceutical, and environmental applications .

For the dialysis technician, infection control officer, and water quality specialist, the Bluetooth Pen Meter (DORP1+) enables rapid, on-site ORP measurement to verify disinfection efficacy in purified water systems, dialysis fluids, and pharmaceutical process water—critical parameters for ensuring patient safety during renal replacement therapy and drug manufacturing. The replaceable electrode design extends instrument service life, while the IP67 rating ensures reliable operation in harsh field environments.

Key features include multi-color backlit display with reading stability indicator and automatic data lock when stable (smiley icon), power-on self-diagnosis function, low battery indicator, user-configurable automatic shut-off time and backlight duration, and compatibility with CH, USA, and NIST calibration standards. The Bluetooth connectivity allows wireless connection to a mobile application with two-way control, unlimited data storage, graphical display modes (chart, curve, dial, and normal), graphic navigation operation guides, calibration reminders, measurement object identification management, timed storage, and high and low value warning settings.

For the patient, accurate ORP monitoring of water used in dialysis and pharmaceutical manufacturing ensures that critical treatment fluids meet stringent safety and quality standards—preventing potential harm from improperly treated water and supporting the production of safe, effective medications.
