Offers a complete pressure gauge with calibration capabilities. With a precise 0.05% full scale accuracy and large 5 digit resolution, this gauge can be used in critical industrial applications where precision is most important. This versatile gauge only requires one 9V battery or power adapter and can operate up to 5,000 working hours.

Designed for determining the state of an inline filter. Determines the pressure drop on either side of a filter through its 1/8" female NPT pressure connections, and relates the value to one of three zones: clean, change, or dirty. Suited for filter applications, line loss, valve drop, and other applications where a simple indicator is needed.

Perfect for applications where corrosion resistance is necessary, these gauges are an economical choice where ambient corrosion and vibration are a concern. Features stainless steel case and ring for excellent protection from harsh processes, and are suitable for all fluids that are compatible with brass and bronze.

The direct reading scales eliminate troublesome conversions. The scales are brushed aluminum, coated with epoxy and the graduations are on both sides of the indicating tube. Special integral flow guides stabilize the float throughout the range to keep it from hunting or wandering in the bore. The float is highly visible against a white background.

The 4-digit LCD can display readings in common English and metric units so conversions are not necessary. The simplified four button operation reduces set up time and simplifies calibration with its digital push button zero and span. All models are factory calibrated to specific ranges.

Designed to measure and control positive, negative, or differential pressures consisting of non-combustible and non-corrosive gases. The gauge reading is independent of switch operation, and switching status is visible by LED indicators located on the front and rear of the gauge. Setpoints are adjusted with push buttons on the back of the unit.

Features a high ±0.25% or ±0.5% full-scale accuracy, and the four-digit digital display will reduce the potential for errors in readings. The gauges are battery-powered and have an auto-shutoff to conserve battery life, as well as a four-button keypad that allows easy access to features.

Movable dial with blue pressure markings and red temperature markings make the instrument easy to read. Pressure is indicated in both psi and kPa, while temperature is measured in both Fahrenheit and Celsius. Series TRI comes in three different connection options including lower mount, center back mount, and center back mount with extension shank.

Designed for pressure, vacuum, and differential pressures. The dual scaled adjustment knob in inches water column and pascals allows changes to the switching pressure to be made without a pressure gauge. The ADPS/EDPS is available with settings from 0.08 in w.c. (20 Pa) up to 20 in w.c. (5000 Pa).

Features field adjustable set point and gold inlay contacts. Air or other compatible fluids can be used on the "high side". The lightweight and compact size make the MDA ideal for any application with space constraints. Applications include industrial, HVAC/R, pump and motor control, medical, automotive, pools and spas.

The Series MDS Pressure Switch is designed with a double diaphragm to protect false actuation due to shock and vibration. This low cost pressure switch has a minimum 20 million cycle life expectancy, and an extremely fast response time, making this an ideal device for OEM orders.

The Mercoid D Series is one of the world's broadest lines of pressure switches. Whatever your application might be, it is most probable it can be fully satisfied with a D Series pressure switch.

Wetted materials of 316 SS and fluorocarbon ensure great chemical compatibility with a wide range of process media. The open case style is perfect for panel mounting applications like pump skids. Field installable weatherproof enclosure is available in polycarbonate offering a low cost weatherproof switch.

Designed for controlling pressure with higher current capacity. These switches are used widely in steam cleaners, steam irons, and other pressure control systems. It provides SPDT contact and Series A9 Pressure Switches utilize high-quality miniature snap-action switches.

Compact instrument for air or other low pressure applications. Visible set point and external adjustment add convenience. Used on air, non-corrosive gas or liquid service compatible with wetted parts. Unit also available in weatherproof and explosion-proof housing.
