Fumigation is an essential process for controlling and eliminating pests in agricultural products, raw materials, and wooden packaging. Common fumigants include Methyl Bromide (MB) and Phosphine (PH₃).

To ensure the highest effectiveness of fumigation, it is critical to use accurate gas measuring instruments and dispensers. However, one important factor often overlooked is calibration. Regular calibration is the key to maintaining quality, safety, and compliance.

 

Why should fumigation instruments be calibrated?

Calibration ensures that instruments continue to provide accurate readings according to standards. Without regular calibration, measurements may deviate, affecting both quality and safety.

Key reasons for calibration include:

     • Accuracy: Ensure gas concentration readings (ppm) reflect actual conditions for effective fumigation performance.

     • Safety: Avoid premature re-entry into fumigated areas due to false low readings.

     • Reliability: Calibrated instruments provide credible data for fumigation reports and certifications.

 

Essential instruments for fumigation calibration

✅ Dispenser

A device for delivering Methyl Bromide gas in precise quantities based on pre-calculated formulas. Inaccurate dispensing can lead to ineffective fumigation or safety concerns.

✅ Fumiscope

An instrument for measuring Methyl Bromide gas concentrations inside the fumigated space. Ideal for monitoring gas levels before reopening the area or during the fumigation process.

✅ Uniphos Fumisense Pro

A high-precision digital Phosphine gas detector, suitable for environments that require strict gas control—such as silos or sealed storage areas.

  

How often should instruments be calibrated?

Instrument Type	Calibration Interval
Fumiscope	Every 6–12 months
Uniphos Fumisense Pro	Every 6–12 months
Dispenser	Every 3 years

Note : For instruments used frequently, exposed to dust, humidity, or frequent transport, earlier calibration may be advised.
