The DPI 800 Series is a complete range of advanced, robust and simple to use hand-held instruments. Highly cost effective, these tools are ideal for test/calibration of many popular process parameters. Advanced features and technical innovations address more  applications in less time and deliver results you can rely on.

All-inclusive accuracy
Can be relied on from one year to the next, even in tough environmental conditions (see specifications)

Dual sensor configuration
Extended measurement range and simultaneous two channel reading (P1 and P2 or P1 - P2)

Stainless steel sensor construction
Available for compatibility with a wide range of fluids and gases (refer to range table)

Programmable leak test
Reports the pressure drop and leak rate 

Advanced features
Hold, maximum/minimum/average, alarm, and tare facilitate troubleshooting

Pressure instrument and loop maintenance

DPI 802 pressure loop calibrator
Provides simultaneous pressure and mA measurement for transmitter and loop maintenance

Dual readings
Simultaneous measurement of pressure and mA for transmitter calibration and loop maintenance

24V loop power supply
Energizes transmitters and control loops

Automatic switch test
Captures open/closed trip values providing a fast and highly accurate “safety system” check

HART resistor
Can be switched into the loop when required by a HART digital communicator and avoids the inconvenience of carrying a 250 Ω resistor


Pressure test and measurement

DPI 800 pressure indicator
The ideal tool for pressure test and measurement

Pressure ranges
10 in H2O to 10,000 psi (25 mbar to 700 bar) including vacuum options

IDOS™ flexibility

Intelligent Digital Output Sensor (IDOS)
Universal pressure modules are available from 10 in H2O to 10,000 psi (25 mbar to 700 bar).

Total flexibility
IDOS modules can be used with any compatible instrument; for example, a DPI 812 RTD loop calibrator can become a fully featured pressure calibrator.

Plug and play
Modules are interchangeable between instruments, requiring no set-up or instrument calibration.

Range expansion
Achieved by adding modules (please refer to the IDOS Universal Pressure Module datasheet).

Data logging upgrade and RS232 lead Log data periodically (1 s to 23h 59m 59s) or manually by key press. 

Review data on-screen or upload to a PC via the RS232 interface. 

No software purchase is necessary as standard Microsoft® applications provide data transfer (HyperTerminal) and analysis (Excel). 

Alternatively, print directly to a compatible serial printer. Real time clock with date. 

Memory: 1000 single or 750 dual reading screens with date and time. Header tag: 6 user characters to identify groups of readings. 

RS232: 19200 baud, 8 data bits, 1 stop bit, no parity, Xon/Xoff. Data output: comma separated ASCII.
