TVA2020 Toxic Vapor Analyzer

Product Description

Thermo Scientific TVA2020 Toxic Vapor Analyzer

The Thermo Scientific™ TVA2020 Toxic Vapor analyzer is the only intrinsically safe, portable field analyzer using both Flame Ionization Detection (FID) and Photo Ionization Detection (PID) technologies.

Features:

• Dual FID/PID technology
• Bluetooth enabled
• Lightweight and compact design
• Easy to service in the field
• No PC based software required

Specifications:

Accuracy

• FID Instrument – ±10% of reading or ±1.0 ppm, whichever is greater, from 1.0 to 10,000 ppm.
• PID Instrument – ±20 % of reading or ±0.5 ppm, whichever is greater, from 0.5 to 500 ppm.

Repeatability

• FID Instrument – 2% at 500 ppm of methane
• PID Instrument – 1% at 100 ppm of isobutylene

Linear range

• FID Instrument – 1.0 to 30,000 ppm of methane
• PID Instrument – 0.5 to 2,000 ppm of isobutylene

Response time

• PID Instrument – Less than 3.5 seconds for 90% of final value, using 500 ppm of isobutylene
• FID Instrument – Less than 3.5 seconds for 90% of final value, using 10,000 ppm of methane
