Crystal M1 Digital Pressure Gauge
The Crystal M1 digital pressure gauge delivers stable accuracy at 0.2% of reading, ensuring dependable performance across various applications.
Description
The M1 is the little brother to the XP2i digital gauge, utilising the same sensor as the XP2i. It has similar features to the XP2i but in a smaller, lower cost, robust package.
The m1 digital pressure gauge delivers stable accuracy at 0.2% of reading, ensuring dependable performance across various applications. The m1 is an affordable solution that doesn’t compromise on quality. Whether monitoring pressures in industrial environments or performing routine maintenance, the m1 offers the precision and features you need at a cost that fits your budget.
A perfect gauge for simple testing work where you don’t need all the great features of the XP2i, but still want accuracy, so you know your readings are correct.
A number of clients have the M1 gauge as their only testing gauge, so it just sits in their tool box ready to use for any pressure.
The M1s have an accuracy of 0.2% of Reading Accuracy from -10 to 50°C, so makes for a great gauge for onsite testing of hydraulics, as well as pipe pressure testing.
Each M1 digital pressure gauge comes complete with a rubber boot. Gives you that little extra protection. Plus each M1 can be calibrated and adjusted by CPS – then you really know the measurements you are making are 100% correct.•
• Unmatched Durability: Designed to withstand the rigors of industrial use, the m1 gauge’s accuracy is unaffected by dropping, over-pressure, vibration, temperature fluctuations, or rapid pressure changes.
• Versatile 30 psi Digital Manometer: Available as a 30 psi digital manometer, the m1 gauge is ideal for low-pressure applications where accuracy is critical. Its versatility allows it to replace up to five 0.25% mechanical gauges, providing greater efficiency and cost savings.
• Long Calibration Interval and Battery Life: With a 2-year recommended calibration interval and up to 3 years of continuous battery life, the m1 minimizes maintenance requirements, saving you time and reducing operational costs.
• User-Friendly Display: The m1 features a bright backlit display with extra-large numbers, making it easy to read in any lighting condition.
• Protective Boot and Replaceable CPF Adapter: The included protective boot safeguards the gauge from everyday wear and tear, while the replaceable CPF adapter shifts the wear to an easily replaceable component, further extending the gauge’s lifespan.
The m1 digital pressure gauge is the perfect blend of affordability, accuracy, and durability. It offers a cost-effective solution for professionals who require reliable pressure measurements without breaking the bank. With its wide range of features, including a long battery life, user-friendly display, and robust design, the m1 is an excellent choice for those looking to upgrade from mechanical gauges or add a versatile tool to their equipment lineup.

Technical Information
Technical Information
The M1 comes complete with a protective rubber boot. It is IP 65 rated so will handle being used outdoors.
Now that the M1’s also come with the Crystal CPF fitting system as standard we can do both ¼ NPT and ¼ BSPP ex-stock. Only available in Bottom entry.
The pressure sensor is fully isolated so can be used on fluids compatible with 316 Stainless Steel, it will also handle pulsing pressure with ease, you won’t damage this gauge due to over pressure either. If you damage the gauge due to overpressure we will replace the unit free of charge, We are that confident you can’t mess them up!
Each Crystal product is very easy to use and the M1 is no exception, It is very easy to change pressure units, turn on or turn off the peak hold function. It’s a menu based system; just scroll through the menu and select what you want and then change or remove it, nothing could be easier! Even changing the batteries is easy.
Unlike lower cost gauges you will not damage this gauge if you drop it 2 meters onto concrete, the case and stem won’t break they are very robust gauges.
Like other Crystal products the M1 is also a percentage of reading device; which means at a certain pressure the accuracy is of that pressure where other gauges are of full scale.
Lets take a 100 PSI M1 gauge at 40 psi the worse the gauge could be, accuracy wise, would be 40 PSI x 0.2% – 40 PSI +/- 0.08 PSI which is pretty good. Now lets say the gauge was a full scale device so at 40 PSI it would be 100 PSI x 0.2 = 0.2 PSI
So 40 +/- 0.2 PSI. So at the same pressure the M1 is over 2 times more accurate than the of full scale device of the same range. Only Crystal gauges do of reading devices, the benefit of this is the useable range is extended – it’s like having 5 gauges in one.
Add in temperature compensation and no other gauge comes close.
Temperature compensation is a function where the gauge measures the sensor temperature and compensates for it, as temperature effects the accuracy of all gauges – digital or mechanical. Crystal gauges take this into account and adjusts the reading based on models to what the actual pressure should be. This is a big advantage! NO body else does this is such a small compact gauge. Allows for even higher accuracies.
