Correct Storing and Handling Standards

T-CAL standards should always be stored in their original vial.•

Store standards between 5 and 25°C (avoid prolonged exposure to tem-•

peratures exceeding 35°C).

Store away from direct sunlight. •

Always allow the standard to acclimatise to ambient instrument tempera-•

ture before use (not to exceed 35°C).

T-CAL Standards have a shelf life of minimum 12 month if stored cor-•

rectly.

Using <0.1 NTU Standard

After delivery allow the vial to stand for least 24 hours before use.

Never shake or invert this <0.1 NTU standard.

If the standard has been shaken it can take several hours for all the bub-

bles dissipate and we suggest the vial is left for at least 24 hours as outlined

above.

If the standard has been inverted accidentally wait at least 15 minutes before

using.

Note: These instructions apply to all standards excepted the <0.1 NTU stand-

ard. If you are using the <0.1 NTU standard follow the instructions above.

These instructions apply to standards that have been sitting undisturbed for

more than one week or to new standards.

Shake the standard vigorously for 2-3 minutes.1.

Let the vial stand undisturbed for 5 minutes.2.

Invert the vial between 5-10 times.3.

Immediately place the vial in the sample chamber and wait for 1 minute 4.

(count down).

Preparing and Using Standards – frequent use

1.1 General description

The TB300 IR is a portable turbidity meter, based on the requirements of ISO 7027 (Water

Quality – Determination of Turbidity). The instrument works with rechargeable batteries as

well as with mains. As soon as the TB300 IR is connected with the adapter to the mains the

batteries are charged.

The instrument features auto ranging over the range of 0.01 to 1100 NTU/FNU.

The turbidimeter is supplied in a case complete with accessories and spares. Calibration

Standards guarantee stability and reproducibility of the results. Always replace the cover on

the sample chamber to protect against dust.

It is possible to update new software applications via internet (www.lovibond.com).

Please ﬁnd detailed information at our homepage on the download-area.

1.2 Operating principles

The instrument measures turbidity in the range 0.01 to 1100 NTU/FTU featuring auto ranging.

The light source is an infrared LED (light emitting diode) with a wavelength of 860 nm.

The emitted light is reﬂected by turbidity in the sample. The scattered light will be detected

at an angle of 90° by a photodiode.

This principle is part of ISO 7027.

The international Reference Standard for turbidity is a Formazin solution. Results related to

these standards are indicated as FNU (Formazine Nephelometric Units).

TurbiDirect_5c 11/2015

1.3 Factory calibration

The turbidimeter TB300 IR is factory calibrated with Formazin Primary Standard and does not

require user calibration before use (see chapter 2.3.5 User calibration).

1.4 Important Notes

1.4.1 Guidelines for turbidity measurements

a) Vials and caps should be cleaned thoroughly after each test to avoid interferences. Minor

residuals can cause errors.

b) The outside of the vial must be clean and dry, before starting the test. Wipe the vials with

a smooth cloth to remove ﬁngerprints or waterdrops.

c) The vials must be positioned in the sample chamber with the mark on the vial aligned

with the mark on the instrument.

d) Always perform the test with securely capped vials.

e) Bubbles on the inside of the vial lead to errors

. See chapter 2.3.8.1 Removing bubbles

(Degassing)

f) Avoid spillage of water in the sample chamber. If water should leak into the instrument,

it can destroy electronic components and cause corrosion.

g) Contamination of the lens in the sample chamber can result in errors. Check at regular

intervals – and if necessary – clean the light entry surfaces of the sample chamber using

a moist cloth or cotton buds.

h) Large temperature differences between the instrument and the environment can lead

to errors – e.g. due to the formation of condensation in the area of the lens or on the

vial. For best results, perform tests with sample temperatures between 20°C (68°F) and

25°C (77°F).

i) To avoid errors caused by stray light do not use the instrument in bright sunlight.

j) Use the instrument in a clean, dust-free environment on a table that is free from vibra-

tion / agitation.

1.4.2 Cleaning of vials & sampling containers

Vials, caps and sampling containers should be cleaned thoroughly after each test to avoid

interferences. Minor residuals can cause errors.

Residuals:

The vial must be cleaned according to the type of sample measured.

• Replace scratched vials immediately.

• Rinse vials thoroughly with deionised water after each measurement.

2.1.2 Saving data – Important Notes

The Lithium battery saves data (stored results and photometer setting) if there is no power

from the power supply from the rechargeable batteries or the mains adapter.

Recommendation: Exchange of the lithium battery every 5 years.

Note: When neither mains adapter nor batteries supply energy to the instrument, all stored

data and settings will be lost, if the lithium battery is taken out.

Recommendation: Keep the instrument connected to mains adapter supply while

changing the lithium battery.
