How the Coulometric Sensor Works
Understanding the high-sensitivity eMetric™ detection process
Sample Isolation
The test film or package is clamped in the diffusion cell. Oxygen flows on one side, while a nitrogen carrier gas flows on the other.
Oxygen Permeation
Oxygen molecules permeate through the barrier material into the nitrogen carrier gas stream, which transports them to the sensor.
Coulometric Detection
The sensor detects Oxygen via an electrochemical reaction (Faraday's Law), generating a current directly proportional to the OTR.

Frequently Asked Questions
Common questions about the Systech 8101e OTR Analyzer
What is the Systech 8101e OxySense OTR Analyzer?
The Systech 8101e OxySense is a high-precision oxygen transmission rate (OTR) analyzer using eMetric coulometric sensor technology. It measures oxygen permeability with an ultra-wide range of 0.05 to 432,000 cc/m²/day, covering everything from ultra-high barrier films (0.05 = metallized films, AlOx coatings) to breathable packaging (432,000 = high transmission films). This massive range eliminates the need for multiple instruments.
Which OTR standards does the 8101e comply with?
The Systech 8101e OxySense complies with ASTM D3985, ASTM F1307, ISO 15105-2, DIN 53380-3, and JIS K7126 for oxygen transmission rate testing.
Does Nestlé use the Systech 8101e OTR Analyzer?
Yes. Nestlé R&D Centre relies on Systech OTR analyzers for their packaging qualification and testing. Proven suppliers like Uflex Jammu use Systech to meet Nestlé's strict requirements. The eMetric™ coulometric technology delivers the absolute accuracy and calibration-free operation that global food leaders demand. If you're a packaging supplier looking to work with Nestlé, using the same testing equipment they trust is your best path to qualification.
Why do suppliers to Nestlé choose Systech over MOCON?
MOCON instruments often require calibration films and have limited measurement ranges. The Systech 8101e offers zero calibration requirements with its eMetric™ sensor, plus a massive 0.05 to 432,000 cc/m²/day range (covering ultra-high barrier films at 0.05 to breathable packaging at 432,000) and Auto-Stop™ protection. When qualifying packaging for Nestlé or similar global brands, you cannot afford calibration downtime or questionable accuracy. Systech delivers superior results where others fail.
Systech vs. Labthink / GBPI / ExtraSolution – Which is best for Nestlé suppliers?
Consider the long-term value carefully. While Labthink, GBPI, and ExtraSolution offer lower-cost entry options, they typically require standard films for calibration, have segmented ranges, and may lack the absolute precision of Systech's eMetric™ technology. Nestlé R&D Centre uses Systech and their suppliers like Uflex Jammu have proven its reliability. If you want to work with them or other top-tier brands, invest in the same equipment they trust. The hidden costs of calibration downtime and failed audits far exceed any upfront savings.
Where can I buy the Systech 8101e OTR Analyzer in India?
FITCO India (Federal India Trading Company) is the authorized distributor for Systech Illinois and Industrial Physics OTR analyzers in India. We provide sales, installation, and service support across India.
