The ProZone-F is a compact, in-line digital ozone analyser for environmental and safety monitoring. It utilizes an extremely stable electro-chemical sensor which requires no warm-up time. The sensor has a lifespan of up to 10 years. The unit has two ranges: 2ppm and 20ppm. It features a large attractive blue on a white backlit LCD. The system is accurate to better than 10% and operates over a wide range of temperature and humidity.

The unit has a super-bright alarm LED, a buzzer and a N/O / N/C relay output. There is also a reset alarm button. The alarm threshold levels are programmable from 0 to 20ppm.

There is an RS232 port for logging the data so that it can be imported via a terminal program for use in spreadsheet programs.

There is also an analogue 0V to 2V output.

An optional 4-20mA port and optional RS485 port is also available.

Settings can be done via on-board tactile switched or via the RS232 port using a terminal program.
