Models
PhoCheck+ is available in a number of variants that can be easily upgraded throughout the range – please see details below. Choose the instrument to best suit your requirements.
PhoCheck 1000Ex – low price, entry level PID
The PhoCheck 1000 is a low price, entry level VOC detector with a range of 0.1 - 4,000 ppm for use in non hazardous environments. The instrument is ideal for indoor air quality monitoring and soil contamination assessment applications.
PhoCheck+ 1000Ex – the first of our Upgradeable PIDs
The PhoCheck+ 1000 VOC detector is the first in line of our upgradeable PIDs. Entry priced with simple functioning, the PhoCheck+ 1000 gives you the ability to upgrade throughout the entire PhoCheck+ and FirstCheck+ range of instruments as your business needs change. ATEX approved as intrinsically safe, the PhoCheck+ 1000 detects VOCs with a range of 0.1 - 4,000 ppm.
PhoCheck+ 2000Ex - a data logging PID with PC download for easy data analysis
The PhoCheck+ 2000 VOC detector allows you to store a minimum of 37 hours worth of data logged readings taken every second (over 130,000 individual readings). The instrument has a date and time stamp for download to a PC via an IRDA link for detailed analysis with windows style IonPC software. This is an ideal instrument for indoor air quality and perimeter monitoring applications.
PhoCheck+ 3000Ex - with Health & Safety mode for STEL and TWA monitoring
The PhoCheck+ 3000 VOC detector benefits from an extended detection range of 0.1 - 10,000 ppm and an additional operating mode for personnel health and safety monitoring. The instrument has pre-programmed user selectable STEL and TWA values for the protection of workers.
PhoCheck+ 5000Ex - dynamic detection range of 1 ppb - 10,000 ppm
