- Page 3 90 mm Mounting Holes 122 mm Sample and exhaust ports suit 6mm OD x 4mm ID Soft tubing. IGD Part Number TOC-750S-TBE supplied as 20M coils. Samplers are designed for ambient sampling only Only use conduit/cable entries provided, drilling the enclosure will void any warranty...
- Page 4 Tube work should not allow condensing liquids to trap in the pipework. Where a large amount of condensation may occur consider fitting line traps. Contact IGD for further advice. A variety of End of Line Termination Points Are Available Contact IGD For...
- Page 5 Tocsin 750 Series Addressable Sample Modules are designed to sample using 6mm OD x 4mm ID tubing from locations up to 20M distant from the module. IGD provide EOL (End Of Line) filter modules to prevent dirt and debris from being drawn into the system.
- Page 6 Part Number TOC-750S-PN3 Where termination is required through into cold stores or wet environments IGD advise use of this part number. The rigid tube assembly passes through the wall of the process at an angle. The diameter and angle are chosen to ensure condensed liquids cannot be drawn up into the sampler assembly.

- Page 9 Doc Ref: SL-065 v1.2 pg 9 IGD provide a range of Android based Apps for use with suitable tablets and mobile phones. For control panels these connect directly using bluetooth. For addressable devices it is necessary to make a direct USB cable connection using IGD’s interface cable as indicated below.

- Page 12 Zero and Calibration Doc Ref: SL-065 v1.2 pg 12 The following diagram shows the preferred method to introduce zero and calibration gases to the sampler. The sampler must not be over or under pressurised during the zero or calibration process. With this arrangement set the flow rate from the gas cylinder such that the flowmeter shows 0.5L/Min of gas flow spilling off.
- Page 13 Zero and Calibration Doc Ref: SL-065 v1.2 pg 13 Flow a suitable zero gas (usually Nitrogen) allow the graph/reading to settle (usually 60-90 seconds) and select ZERO to zero the detector Now apply calibration gas as indicated. The graph should show the signal rise as the detector responds to gas and gives a visual indication to show when the reading has stabilised.
