Product catalog summary

Specifications:
The m1M Pressure Gauge is designed for internal pressurized volumes of 295 mm³ (0.02 in³) and can withstand up to 300 PSI. It features a diaphragm surface with a diameter of 106.2 mm (4.18 inches) and various adapter options including 1/4 inch MNPT, MBSP, and M20x1.5.

Accuracy and Calibration:
The gauge has a recommended calibration interval of three years. Accuracy varies with the range: ±0.05% of full scale from 0 to 20% of range, and ±0.25% of reading from 20% to 110% of range. Vacuum accuracy is ±0.5% of full scale.

Operating Conditions:
It operates within a temperature range of -10 to 50°C (14 to 122°F) and is powered by two AA batteries, offering up to 30,000 hours of battery life depending on usage frequency.

Display and Enclosure:
The gauge features a 5-digit screen with a display rate of 4 readings per second. It is housed in a polyester/polycarbonate blend enclosure with an IP65 rating, weighing 331 g (11.7 oz).

Sensor and Materials:
The sensor uses 316 stainless steel and Viton® for wetted materials, with a silicone oil diaphragm seal fluid. It is compatible with various pressure systems and adapters.

Certifications:
The m1M complies with Electromagnetic Compatibility and Pressure Equipment Directives and is approved for marine use under Det Norske Veritas standards.

Range and Resolution:
The gauge supports multiple pressure ranges and resolutions, including 300 PSI, 20 BAR, and 2 MPa, among others.

Ordering Information:
Various models and configurations are available, including options for different adapter types and pump systems. Sample part numbers are provided for reference.

Accessories and Complementary Products:
Accessories include a protective boot and various pump systems. Complementary products for the maritime industry are also available, such as high-pressure hoses and digital test gauges.

Pump Systems:
Details on Systems B and C are provided, including maritime and quick test configurations with various connection fittings and carrying cases.

m1M Pressure Gauge ACCURACY – 3 YEAR RECOMMENDED CALIBRATION INTERVAL 0 to 20% of Range: ±(0.05% of Full Scale) 20% to 110% of Range: ±(0.25% of Reading) Vacuum: ±(0.5% of Full Scale*) * Full Scale = -14.5 psig / -1 bar / -0.1 MPa OPERATING TEMPERATURE Screen: 5 digits, 16.8 mm (0.66") high Includes all effects of linearity, hysteresis, repeatability, temperature, and stability for three years. All models indicate vacuum, but vacuum specification applies to 300 psi / 20 bar / 2 MPa models only. Not recommended for continuous use below -14.5 psi. Refer to XP2i-DP data sheet for gauges that are intended for continuous high vacuum use. Non-condensing. No change in accuracy over operating temperature range. Gauge must be zeroed to achieve rated specification. LCD readable in sunlight with bright backlight. SENSOR DIAPHRAGM SURFACE Display Rate: 4 readings/second Extended Battery Life: 1 reading/15 seconds: 3,000 hours 6,000 hours 1 reading/30 seconds: Uses 2 alkaline AA (LR6) batteries. Use of backlight reduces operating time. Extended battery life is keypad selectable.
