PA600-LR Series Low Range Pressure Sensors
PA600-LR Low Range Industrial Pressure Transmitters

The PA600-LR series of low range pressure sensors are suitable for measuring mBar pressures in gas and liquid media across a wide range of general purpose and industrial applications. The standard the PA600-LR comes with: Viton O-ring, 303 stainless steel case, 316L Stainless Steel diaphragm with Silicon-based sensing element and a ¼"BSP male process connection, but various standard options are available. The PA600-LR series provides a wide choice of electrical outputs from its ASIC-based amplifier circuit, these include 4-20mA, 0-5V, 0-10V, various mV/V, as well as a ratiometric 0.5-4.5vC (10% to 90% of supply voltage) signal that requires a 5V (2.7 - 5.5vDC acceptable).

PA600 Series covers higher range pressure ranges from 500mBar.

Price range : £17.93 - £178.50
Multi-Point Air Velocity Probes & PA267 Differential Pressure Sensor.
Multi-Point Air Velocity Probes & PA267 Differential Pressure Sensor.
A multi-point air velocity system using the PA267 differential pressure sensor and AV-EP or AV-MPS air velocity probes. This system can be used to ensure that recommended flow rates for public buildings and industrial plant are achieved. Suitable for flow ranges of 0 - 40m/s.
Price range : £17.06 - £219.23
DPT-R8 Differential Pressure Transmitter
DPT-R8 Differential Pressure Transmitter
The DPT-R8 is an electronic differential pressure transmitter with eight jumper selectable measurement ranges in one device, from +/-100PA up to 0-7000Pa. The output is selectable as 4-20mA or 0-10V. The units also have the option of an LCD or Auto Zero function.
Price range : £90.00 - £135.89
PS Differential Pressure Switch
PS Differential Pressure Switch
The PS series switches are a cost effective solution for various applications in building automation systems in the HVAC/R industry. The PS series sensor include a field adjustable dial with switching ranges from 20-200 pascals up to 500-4500 pascals and maximum pressure of 50kPa. Switching contacts are rates to 3 amps @ 250vAC, allowing the switch to be used for alarming, or to operate fan motors to maintain pressure or flow ranges. The PS switch is a simple mechanical differential pressure switch which can be used for fan, blower and filter monitoring, clean room pressure monitoring, or valve and damper monitoring.
Price range : £13.40 - £13.40
PA-DPS Differential Air Pressure Switch
PA-DPS Differential Air Pressure Switch
The PA-DPS range of differential air pressure switches are suitable for low differential pressure switching applications. These units are ideal for providing indication of fan status or filter dirty conditions in air, non-combustible, non-aggressive gases in air conditioning and ventilating installations. Adjustment ranges are available from 20 Pa up to 2,000 Pa with a max operating pressure of 5,000 Pa. The switching knob is mounted under the cover to avoid tampering and the scale is individually laser etched for high accuracy. Units are available in standard IP54 or optional IP65 housings and come complete with a Duct Fixing Kit including 2m of tubing, two pitot tubes and fixing screws.
Price range : £4.14 - £45.92
PA-699 Multi-range Differential Air Pressure Sensor
PA-699 Multi-range Differential Air Pressure Sensor
The PA-699 is a differential pressure sensor incorporating a proved ceramic fulcrum lever technology. They deliver calibrated, temperature-compensated sensor signals, available as standard voltage or current outputs. They are ideal for registering low air flow in air conditioning systems and for the measurement of fine pressures in environmental, laboratory and clean room application (air and non corrosive gases).
Price range : £190.54 - £190.54
9200 Series Handheld Differential Pressure Meter
9200 Handheld Differential Pressure Meter
The 9200 Series meters are a range of compact, general purpose differential pressure meter designed specifically for monitoring low range differential pressures using 4mm tubing to barbed stainless steel connectors on the handheld meter.
Price range : £14.00 - £100.00
MC 4.0 ManoAir Pressure Gauge
MC 4.0 ManoAir Pressure Gauge

The MC 4.0 ManoAir is part of the MC 4.0 range but comes with a pressure sensor module that allows the unit to measure absolute or differential pressure. The MC 4.0 ManoAir includes an internal logger for up to 1 million readings and pressure module for connecting 2 sensors. The pressure modules are used for precise flow and differential pressure measurement of gaseous media on filters and in pitot tubes in the ventilation duct. They are used in heating, ventilation and air conditioning as well as in clean rooms. Two pressure modules are available for the measuring ranges ±2000 Pa and ±20 kPa, which can be exchanged with a single movement.

The MC 4.0 ManoAir is the replacement for the ManoAir 100 Digital Manometer.

Price range : £486.25 - £1,115.52
Lab 4.0 Manometer
Lab 4.0 Manometer

The Lab 4.0 is an instrument suitable for gas analysis in all laboratorial activities. The instrument can be used for differential pressure manometer for very small measuring areas, Particle Measurement System or Environmental Gas Analysis with Volatile Organic Compound (VOC) and Indoor Air Quality (IAQ) Sensors, plus ambient sensors for barometric pressure, temperature and humidity.

Price range : £399.55 - £13,550.00
