General Description

The HI 93734 meter measures the Free and Total Chlorine (Cl2) content in water and wastewater.

The meter uses an exclusive positive-locking system to ensure that the cuvet is in the same position every time it is placed into the measurement cell.

The reagents are in powder and liquid form and are supplied in bottles and powder packets. The amount of reagent is precisely dosed to ensure maximum repeatability.

Display codes aid the user in routine operations.

The meters have an auto-shut off feature that will turn the instrument off after 10 minutes of non-use.

Display Code Guide

This indicates that the meter is in a ready state and zeroing can be performed.

Sampling in Progress. This prompt appears each time the meter is performing a measurement.

This indicates that the meter is in a zeroed state and measurement can be performed.

A zero reading was not taken. Insert a sample before adding reagent and press ZERO.

Under range. A blinking "0.00" indicates

that the sample absorbs less light than the zero reference. Check the procedure and make sure you use the same cuvet for reference (zero) and measurement.

	Over range. A flashing value higher than
	the maximum concentration readable (see
	specifications) indicates that the sample
	absorbs too much light, meaning that the
	concentration is too high. Dilute the
	sample.
	Light over range. The cuvet is not inserted
	correctly and an excess ambient light is
	reaching the detector. If the cover is
	properly installed, then contact your dealer
	or the nearest Hanna Customer Service
	Center.
	Light under range. The zero sample is too
	dark for proper zeroing. If this is not the
	case, contact your dealer or the nearest
	Hanna Customer Service Center.
V	The "V" indicates that the battery voltage
	is getting low and the battery needs to be
	replaced.
	This indicates that the battery is dead and
	must be replaced.
	Note: once this indication is displayed,
	the meter will lockup. Change the battery
	to restart.
