- Design adheres to the principle of no moving parts, no moving
sample in sulfur recovery applications.
- The TLG-837 uses solid state diode array spectrophotometer
for detection, measuring complete spectrum from 190nm to 1100nm
with 1nm resolution
- The TLG-837 uses fiber optics to transmit light to and from
the detector, allowing the electronics to be physically separated
from the probe.
- a very long life pulsed xenon lamp or a low noise Deuterium
lamp. The light is focused onto the tip
- The analyzer measures a complete spectrum of the process and
analyze the data via a calibration method to give very accurate
and reliable concentration readings.
- Sampling - Patent-pending-cold-finger probe
- The inner one is basically a “cold finger” that
is designed to remove most of the sulfur vapor in a controlled
manner.
