Instrument Functions:

Data Input- each sample captures a unique ID number, date, time and reading in addition to user defined sample ref and location data.

Sensitivity- the instrument has 3 sensitivity settings accommodating a wide range of Tryptophan concentrations. Concentrations can be measured from 0.025ppm to 25.0ppm.

Backlight- may be turned on and off as light conditions require, the backlight will automatically be turned off after 5 minutes to preserve battery life.

Auto Sampling- using a flow cell and pump the instrument may be set up to carry out a series of measurements over a specified period at user defined intervals. The results may be written to either the internal memory or to an external data logger.

Internal Memory- may be downloaded via an RS232 port. A 9 pin RS 232 to RS232 / USB output is provided to connect the SMF4 to either a PC or data logger. PC requires Windows 98/2000/XP/7. The internal memory may also be cleared using the download function.

Set Date/Time- date and time are set in dd/mm/yy and hh/mm

Battery Information- the SMF4 is powered by NiMH rechargeable batteries, which give a useful operating period of approx 10hrs. Approx 12hrs recharge time required using provided charger. Battery life is shown by a battery level indicator icon on the LCD display.

Sample Cell- cell holder accepts standard fluorescence cells of 10 x 10 x 40 mm and will accommodate flow through cells for auto sampling.

Instruments are currently in use in the UK, USA, France, Australia and South Africa.
