Supported Applications
The Omega PHH253 series comprises portable pH/mV meters with Automatic Temperature Compensation (ATC), designed for quick and accurate measurement of pH, mV, and temperature in field or laboratory settings. The primary application is the monitoring of liquid quality parameters using a handheld instrument.
Operating Conditions & Performance
The PHH-253 meter operates with an automatic ambient temperature range of 0 to 100°C (32 to 212°F). Measurement capabilities cover the following ranges:
- pH: 0 to 14 pH units
- mV: ±2000 mV (absolute)
- Temperature: -100 to 100°C (-148 to 212°F)
Performance specifications include the following accuracy and resolution values:
- pH Accuracy: ±0.02 pH units; Resolution: 0.01 pH units
- mV Accuracy: ±0.05 % or 1 digit; Resolution: 1.0 mV
- Temperature Accuracy: ±0.3°C; Resolution: 0.1°C
The device features an LCD display and supports one- or two-point manual pH calibration.
Configuration Options
The series is offered as the PHH-253-KIT, which includes a portable meter, carrying case, user's manual, epoxy-bodied general purpose pH electrode, and temperature probe. The instrument connects to sensors via specific interfaces:
- pH Electrode Connection: BNC
- Temperature Probe Connection: 3 pole, 3.5 mm (0.138") diameter jack
- Reference Electrode Connection: 4 mm (0.157") diameter
The meter is powered by one 9 V battery (included). The overall dimensions are 145 L x 81 W x 38 mm H (5.7 x 3.2 x 1.5"), and the weight is 272 g (9.6 oz).
Key Product Differences
The PHH-253 series includes specific replacement parts and accessories to support maintenance and expanded measurement capabilities:
- PHE-4201: Clear, epoxy-bodied, gel-filled combination replacement electrode
- PHAT-253: Replacement temperature probe
- ORE-1411: Double junction ORP probe (accessory)
- FW-300: Reference Book: Water Wells and Septic Systems Handbook (accessory)
The series carries CE approval. A 1-year warranty applies to electronics only.
