(mg/L, ppm, or no units)
Display resolution-turbidity: 4 digits; decimal point moves
from x.xxx to xxx.x
Display resolution-TSS: 4 digits; decimal point moves from
x.xxx to xxxx
Calibration methods: user-prepared standard, commercially
prepared standard, or grab sample. For total suspended
solids user must provide a linear calibration equation.

(Ordinary Location only)
Inputs: Choice of single or dual input
RFI/EMI: EN-61326
LVD: EN-61010-1
Outputs: Single input analyzer has single output. Dual input
analyzer has dual outputs. Outputs are 0-20 mA or 4-20
mA isolated. Maximum load is 600 ohms. Output dampen-
ing with 5 sec time constant is user-selectable.

FLOW CHAMBER
Dimensions: 18.1 in. x 4.1 in. diam. (460 mm x 104 mm diam.)
(approx.)
Wetted materials: ABS, EPDM
Inlet: compression fitting accepts 1/4 in. OD tubing; fitting can
be removed to provide 1/4 in. FNPT
Drain: barbed fitting accepts 3/8 in. ID tubing; fitting can be
removed to provide 1/4 in. FNPT. Must drain to atmos-
phere.
