
The flow-through cuvette is rated for a flow of 100ml/min. - 1 liter/min.
(0.026-0.26Gal/min).

The integral pressure regulator is rated for a MAXIMUM pressure of 7 bar

3.3.1 Initial Assembly
The IN and OUT tubes must be connected to the MTOL+ before the
system is connected to the sample water source and drain.
1. Identify the IN tube. This is the tube with the white ratcheting clamp.
2. Install the IN tube between the sensor mounting earmarked IN and the
flow head connection marked IN. Secure both ends tightly.
3. Identify the OUT tube. This is the tube with the rotary backpressure valve.
4. Install the OUT tube between the sensor mounting earmarked OUT and
the flow head connection marked OUT. Secure both ends tightly.
3.3.2 Connection of MTOL+ to System Plumbing
Requirements:

Use ¼ inch OD flexible tubing (polyethylene or polypropylene) for connecting
the MTOL+.
Use Opaque tubing if tubing may be exposed to sunlight. This
will help limit algae growth.

MTOL+ has push-to-connect fittings for water inlet and drain connections.
