Lion Mark II Formaldemeter

• Monitoring formaldehyde levels in laboratories and cleanrooms.
• Assessing air quality in industrial settings where formaldehyde-containing resins or chemicals are used.
• Ensuring health and safety compliance in healthcare facilities and mortuaries.
• Evaluating indoor air quality in offices or residential buildings after renovation or furnishing.
• Research and development involving formaldehyde-releasing materials.

Measurement Principle

Typically electrochemical or photo-ionisation detection.

Detection Range

Commonly 0-10 ppm or 0-100 ppm, depending on the model variant.

Response Time

Typically within 30-60 seconds for stable readings.

Power Supply

Often battery-operated for portability, commonly using AA or rechargeable battery packs.

Calibration

Requires regular calibration, typically with certified formaldehyde gas standards.

Filter Type

Units of this type often utilise replaceable phenol filters to mitigate cross-sensitivity.

Operating Temperature

Typically designed for use in ambient laboratory or industrial temperatures, e.g., 0-40°C.

• What is the typical accuracy of a Formaldemeter Mark II?

  For this class of equipment, accuracy is generally within ±10% of reading or ±0.2 ppm, whichever is greater, provided it is regularly calibrated and maintained.

• How often does a Formaldemeter Mark II require calibration?

• Can this unit detect other gases besides formaldehyde?

• Are replacement parts, such as phenol filters, readily available for this model?

• Is this unit suitable for continuous monitoring?

Gas analyzers and detectors are regarded as essential precision instruments in pharmaceutical and biotech laboratories. Buyers typically prioritise calibration records and maintenance history when purchasing used equipment. These instruments are valued for their accuracy, repeatability, and reliability in critical analytical processes. Key considerations include ensuring proper documentation of service intervals, verifying sensor functionality, and confirming compatibility with existing laboratory systems. Well-maintained units often perform comparably to new equipment at considerably lower cost, making them attractive for budget-conscious facilities requiring validated analytical capability.
