Digital Manometer DM-3700
Wide pressure range from 200 Pa to 50 MPa. Digital manometer with built-in high-precision sensor with excellent overpressure characteristics.
～Features～ ● A variety of sensors for differential pressure, gauge pressure, pressure/vacuum, and absolute pressure are available. ● Absolute pressure and pressure/vacuum are optional. ● Covers wide range from micro-pressure of 200 Pa to extremely high pressure of 50 MPa. ● Comparators, Auto-Zero, Display Hold, etc. ● ISO/IEC 17025 calibration required by TS16949 available. ● External sensor optionally available, which allows shorter piping to the work. ● Portable and fixable with dedicated brackets. ● Multi power source: 100 to 240 VAC.
basic information
~Functions~ Digital display: 0000 to ±9999 Comparator output: 5 outputs: Limits (HH, HI, LO, LL) and GO 8 channels: 8 programmable comparators Display Hold: The reading can be held at any time. Peak value hold / Bottom value hold: The peak value in pressure rise and the bottom value in pressure drop can be held. Auto-Zero: With the current value set to zero, pressure changes after that can be displayed. Analog output: The analog voltage corresponding to the Pressure Range is output. (Amplifier optionally available) Digital output: BCD output board is optionally available. Data can be transferred to external equipment. Keyboard lock: The keyboard can be locked to prevent false operation.

Cosmo’s Air Leak Testers began with the automation of cylinder block airtightness tests for engines in 1970. Our products are utilized in various fields including automotive parts, gas, water supply, medical, electrical, electronics, and food. In line with the overseas expansion of Japanese automakers, we began our own overseas expansion in 1983. We now have 24 sales and service offices in 13 countries. We are offering proposals and providing after-sales services overseas as in Japan. Currently, in order to support the electrification of automobiles, our products are being used for leak testing of parts for electrification such as battery cases and inverters as well as for fitting testing of electric power connectors. We are contributing to the efforts by our customers to prevent emissions of CO2. In various regions of South and Southeast Asia, we are donating pressure measuring equipment to technical schools to improve the quality of education and exchange technologies with local machinery manufacturers. We have been making every effort to help improve the industrial base through local manufacturing of high-quality leak testing equipment.
