Anton Pro 90° Bend Flue Gas Probe C03738-B fits flue ports that straight probes miss and keeps sampling clean and steady. It supports Sprint Pro analysers for safe and quick checks on boilers and heaters without fuss. The bend helps you reach awkward terminals and keep the seal sound as you work. The probe stays light in the hand and simple to control on tight jobs.
Design and reach
The 250 mm insertion length helps you position the tip at the right spot and repeat your readings with the depth gauge. The 6 mm stainless shaft slides in cleanly while the moulded handle gives a firm grip and good control. The 90° geometry adds access without forcing the hose to kink and the bend section remains compact. You keep a steady approach and reduce strain during repeated tests.
Sampling and protection
The in-line water trap catches condensate before it reaches the analyser and the dust filter blocks fine debris from entering the pump. A secondary water block at the connector gives extra protection in harsh, wet flues and helps extend service life. The built-in K-type thermocouple supports temperature checks right at the sample point and the long hose gives comfortable working distance at the appliance. These details improve reliability on both installs and maintenance days.
This probe works across the Sprint Pro range so it drops into your kit without change. You move from one appliance to the next with fewer resets and fewer parts to swap. The build feels robust yet stays easy to handle on site. Your workflow stays quick and your results stay consistent.
