1. INTRODUCTION

1.1. SCOPE

This manual contains technical specifications, detailed description and maintenance information,

parts lists, and diagrams for the Guildline Instruments 8400B AUTOSAL "Laboratory

Salinometer".

1.2. UNIT DESCRIPTION

1.2.1. APPLICATION

The instrument is semi-portable, semi-automatic, and is used in the land based or sea-

borne laboratory to determine salinity levels in saline samples by measuring the

equivalent conductivity ratio to a standard seawater sample.

1.2.2. PHYSICAL LAYOUT

The instrument is enclosed in an aluminum cabinet measuring 68 cm high, 53 cm wide

and 55 cm deep; maximum total weight is approximately 70 kg. The cabinet incorporates

a flushmounted handle on each side for easy carrying and is designed for bench

mounting. The instrument chassis is held in place in the cabinet on four track slides for

easy withdrawal from the front by removing four polished binder head screws.

Removing the three left-hand screws allows the front panel to hinge out. All primary

controls, indicators, and the adjustable sample bottle holder, cell inspection window and

external tubing connections are located on the front panel. Power input, 120/240 volt

switching and the BCD OUTPUT connector are located on the rear panel.

1.3. CARE AND HANDLING

1.3.1. USAGE

Although this instrument is designed for high precision measurement it is quite rugged.

It requires only reasonable care and good maintenance practices to ensure optimum

performance. It can withstand continuous operation and if required, long periods

between operations.

1.3.2. CARRYING/TRANSPORTATION/STORAGE

The handles provided on the sides of the cabinet provide the easiest, safest means of

lifting the instrument. Use the valves provided to drain the internal fluids and so reduce

weight, prevent possible leakage during transportation, and to prevent damage if

subjected to below freezing temperatures. A tank drain plug is provided with the unit for

eliminating drips from the nipple during transportation.
