Gastec 1-Butanol Detector Tube No. 114

Quick guide from the manual

The Gastec No. 114 1-Butanol Detector Tube is designed for detecting 1-Butanol in air or industrial areas. It must be used in conjunction with a Gastec Gas Sampling Pump to ensure accurate results. The tube contains a reagent that changes color from yellow to pale blue upon reaction with 1-Butanol.

Safety Precautions

• Always wear eye protection when breaking tube ends.
• Do not touch broken glass or reagent with bare hands.
• Use only Gastec detector tubes with Gastec pumps to ensure accuracy and safety.
• Store tubes in a cool, dark place.

Measurement Procedure

1. Check the pump for leaks by inserting a fresh sealed detector tube.
2. Break the tips off a fresh detector tube using the pump's tip breaker.
3. Insert the tube into the pump inlet with the arrow pointing toward the pump.
4. Align the guide mark on the pump body with the guide mark on the handle.
5. Pull the handle out until it locks (one stroke). Wait two minutes. Repeat this process for a total of 3 pump strokes.
6. Read the concentration level at the interface where the stained reagent meets the unstained reagent.
7. Apply temperature or pressure corrections if necessary.

Corrections

Temperature: Use the provided correction table to adjust readings based on the ambient temperature (0°C to 40°C).

Pressure: Use the formula: (Tube Reading x 1013) / Atmospheric Pressure (hPa).

Humidity: No correction is required for 0-90% relative humidity.

Interferences and Disposal

Alcohols cause positive interference (color change to pale blue). The reagent contains hexavalent chromium; dispose of tubes according to local regulations.
