Page 3: Introduction
The Opti-Check is a small, lightweight, highly durable handheld fluorometer ideal for quick measurements in the field. Dual-channel capability enables measurement for both cooling tower and boiler system applications. Simple to operate, the Opti-Check is a perfect tool for system verification. The Opti-Check can be configured with two channels: Fluorescein, PTSA or both. -

Instrument Operation and Calibration 3.1 Instrument Power Up To turn on the Opti-Check, press the <ON/OFF> button. After a 5 second warm up, the Opti-Check is ready for operation. Pressing the <ON/OFF> button again will turn the unit off or if left idle for 3 minutes the unit will turn itself off to save battery power. -
Page 7: Calibration Procedure
3.4 Calibration Procedure It is recommended for best accuracy, that you always calibrate before performing your sample analysis. The Opti-Check will save the calibration settings for each channel until a new calibration is performed. If the temperature of your samples or the Opti-Check changes significantly, the readings may show a small shift and in this case, you should consider recalibrating. -
Page 8: Sample Analysis
3.4.3 Calibration Check Once the Opti-Check calibration is accepted, press the <DIAG> button to see what your standard to blank ratio is. The standard to blank ratio is defined as the %FS blank as compared to the %FS standard. The %FS signal should be at least 5 times larger than the %FS Blank. -

4.3 Linear Range and Quenching The linear range is the concentration range in which the readout of the Opti-Check is directly proportional to the concentration of the fluorophore in the sample. The linear range begins with the lowest detectable concentration and spans to an upper limit concentration that is dependent on the properties of the fluorescent material and the cuvette optical path length. -

2.2. 4.5 Data Quality The Opti-Check is only as accurate as the standards that are used to calibrate it. This is why it is important to take care when preparing standards, samples, and blank. One should follow good laboratory practices when preparing all solutions and samples. -

Fluorescein Dye (PN 10-509) Calibration standard 400 ppb. 5.2 PTSA PTSA is a fluorescent tracer dye that measures in the UV range on the Opti-Check between 365-400nm. It can provide an accurate, cost effective method for monitoring industrial cooling tower applications and it can also be used as a standard for UV sensors. The linear detection range is 0 to 1000 ppb. -
