INTRODUCTION
Congratulations on your purchase of the Dissolved Oxygen/Temperature TRACER.
Units of measure are % saturation, mg/L or ppm for dissolved oxygen and C° or F°
for temperature. Advanced features include data hold, 25 point memory, auto shut off,
automatic temperature compensation, and salinity/altitude compensation.
Careful use and maintenance will provide years of reliable service.
