Tiger LT Handheld VOC Detector

The leading technology of the TIGERLT makes it the most advanced, low-cost handheld VOC detector on the market giving you the most accurate, reliable results you can count on, every time.


The leading technology of the TIGERLT makes it the most advanced, low-cost handheld VOC detector on the market giving you the most accurate, reliable results you can count on, every time. Whether deciding to wear PPE or checking head space for compliance TIGERLT gives confidence that the right decision will be made in all environments, humid or dusty.

This variant of the hugely popular TIGER VOC detector is low on cost but high on performance. Its revolutionary, patented PID sensor technology with humidity resistance and anti-contamination design provide market leading accuracy and run time. Combined with 24 hour battery life, these features maximise field time by minimising erroneous readings in high humidity and drift in harsh environments.

The world’s leading PID manufacturer, ION Science’s PID sensor technology has also received independent verification as the best performing on the market for its speed of response, accuracy and linearity.

TIGERLT accurately detects gases from 0.1 to 5,000 ppm, has the fastest response time on the market of just 2 seconds, and is as quick to clear down. Its push-to-log data logging stores up to 80,000 data points in up to 128 user selectable zones.

The instrument has been designed with the user in mind for ease of use and servicing. Batteries can be replaced in potentially explosive environments due to the innovative Intrinsically Safe design. Low cost filters and lamps can be easily changed in minutes, minimising instrument downtime. Fast battery charging allows the instrument to be fully charged in just six hours.

TIGERLT offers simple, one handed operation even when wearing multiple pairs of thick gloves. Its rugged design and protective, removable rubber boot withstand harsh environmental conditions.

The large, clear back-lit display allows for easy viewing in any light condition. An integrated torch is designed for directing the instrument’s probe into dimly lit areas. The illuminated keypad activates when light is low.

TIGERLT is a ground breaking, low cost entry level PID with all the essential functions you need for VOC detection.The instrument has the lowest running costs on the market with inexpensive disposable parts, lamps and filters.
