All analyzer versions are marked as follows:
MLTx y-CH1 CH2 CH3 CH4 CH5
with
x = analyzer type 1, 2, 3, 4, 5, CAT 200 with
1 = 1/2 19", not thermostatted, external power supply
2 = Field housing, thermostatted, internal power supply
3 = 1/1 19"-housing, thermostatted, internal power supply
4 = 1/1 19"-housing, thermostatted, external power supply
5 = 19", 18 to 21 HU housing, thermostatted, internal power supply
CAT 200 = flameproof enclosure
y = analyzer version T, M, A, R, TE, ME, AE, RE with
T = table top
M = analyzer module, platform mounting
(net/electr. connections from front side only)
A = analyzer module, external installation or platform mounting
(net/electr. connections from rear side or front side)
R = rack mounting
E = extended housing (MLT 1 only)
CH1...5 = measuring method of the individual (max. 5) measuring channels with
IR = measurement at infrared spectral range
UV = measurement at ultraviolet spectral range
VIS = measurement at visual spectral range
PO
2
= paramagnetic oxygen measurement
EO
2
= electrochemical oxygen measurement
TC = thermal conductivity measurement
TEO
2
= trace electrochemical oxygen measurement
