Achieve consistent, trustworthy measurements with +/-5 mV accuracy and 1 mV resolution. This precision level meets the demands of water treatment professionals, laboratory technicians, and quality control specialists who require dependable data for compliance reporting and process optimization. The digital display eliminates analog reading errors, presenting clear numerical values that can be recorded, compared, and trended over time.

3. Compact Handheld Design

Weighing just 50 grams and measuring 155 mm x 31 mm x 20 mm, this portable ORP tester fits comfortably in a pocket or toolkit. The lightweight construction enables extended field use without fatigue, while the slim profile allows easy access to sampling points in tight spaces. Carry it between multiple testing locations from poolside to treatment plant to laboratory bench without cumbersome equipment.

Key Features of the ORP Meter 169E

1. Digital LCD Display

The clear digital screen presents ORP readings in millivolts with instant stabilization. Large numerics ensure readability in bright outdoor conditions and dimly lit treatment facilities alike. The straightforward interface requires no technical training power on, immerse the probe, and read the value directly from the display.

2. Simple Calibration Process

Maintain measurement integrity through straightforward calibration using ORP standard solutions. Regular calibration compensates for electrode aging and environmental factors ensuring long-term accuracy. The simple procedure requires minimal time and no specialized training, keeping the meter operational with basic maintenance routines.

3. Long Battery Life

Powered by 2 x 1.5V button batteries, the ORP meter 169E delivers extended operational life between replacements. The low-power design ensures reliable performance during fieldinspections, remote monitoring assignments, and continuous testing sessions without interruption for battery changes.

4. Durable Sensor Construction

The integrated ORP probe withstands repeated immersion in various water chemistries including chlorinated pools, saline aquariums, and industrial process water. Proper rinsing and storage after each use preserves sensor sensitivity and extends operational lifespan, reducing long-term maintenance costs.

Applications of the ORP Meter 169E

1. Swimming Pool and Spa Water Management

Monitor disinfection effectiveness in swimming pools, spas, and hot tubs by measuring oxidation reduction potential. ORP readings above 650 mV typically indicate adequate free chlorine activity and effective sanitization. Track values throughout the day to optimize chemical dosing, prevent algae growth, and ensure swimmer safety while minimizing chlorine consumption.

2.Aquarium and Aquaculture Systems

Maintain healthy aquatic environments by monitoring the oxidation-reduction potential of freshwater and marine aquariums. ORP levels correlate with water quality parameters including dissolved oxygen, organic waste accumulation, and biological filtration efficiency. Aquaculture operators use ORP data to prevent stress conditions, optimize feeding schedules, and reduce mortality rates in fish farming operations.

3. Water Treatment Plant Monitoring

Verify disinfection performance in municipal and industrial water treatment facilities. ORP measurement complements chlorine residual testing by indicating the actual oxidative capacity of water rather than just chemical concentration. Treatment operators use this data to adjust ozone, chlorine, or UV dosage for regulatory compliance and pathogen control.

4. Reverse Osmosis and Filtration Systems

Evaluate the effectiveness of water purification systems by tracking ORP before and after filtration stages. Declining post-filter ORP values may indicate membrane degradation, carbon exhaustion, or biological contamination requiring maintenance intervention.This proactive monitoring prevents system failure and maintains product water quality.

5. Laboratory and Research Applications

Support chemical research, environmental studies, and quality assurance testing with portable ORP measurement capability. The meter's wide range and reliable accuracy suit educational demonstrations, process development experiments, and field survey campaigns where laboratory benchtop equipment is impractical.

6. Industrial Process Water Control

Monitor cooling tower water, boiler feedwater, and process streams in manufacturing facilities.ORP data guides corrosion inhibitor dosing, biocide treatment scheduling,and waste water discharge compliance. Industrial maintenance teams rely on consistent readings to prevent equipment damage and environmental violations.

Why Choose This ORP Water Tester?

1. Proven Accuracy and Reliability

The +/-5 mV accuracy specification meets professional standards for water quality assessment. Unlike colorimetric test kits that rely on subjective visual interpretation, this digital ORP meter delivers objective numerical data that can be documented, compared against standards, and used for regulatory reporting.

2. True Portability

At 50 grams with pocket-sized dimensions, this is genuinely portable water testing equipment. Compare to benchtop ORP analyzers that require AC power, calibration solutions, and dedicated workspace. The 169E goes wherever water quality questions arise -- field inspections, client sites, emergency response scenarios.

3. Cost-Effective Operation

Eliminate recurring costs of disposable test strips and reagent kits. The reusable sensor and inexpensive button batteries provide ongoing measurement capability at minimal operating expense. For facilities conducting daily ORP checks, this meter pays for itself within weeks compared to consumable-based testing methods.

4. Versatile Application Range

One device serves multiple testing environments -- pools, aquariums, treatment plants, laboratories, and industrial systems. The broad -1999 mV to +1999 mV range accommodates everything from anaerobic digester monitoring to hyper-chlorinated disinfection validation without equipment swapping.
