A. Safety advice

Avoid electrical hazards:

Never use the measuring instrument and probes to measure on or near live parts!

Protect the measuring instrument:

Never store the measuring instrument/measuring cells together with solvents

(e.g. acetone). Do not use any desiccants.

Product safety/ preserving warranty claims:

Operate the measuring instrument only within the parameters specified in the Techni-

cal data.

Handle the measuring instrument properly and according to its intended purpose.

Never apply force!

Temperatures given on probes/sensors relate only to the measuring range of the

sensors. Do not expose handles and feed lines to any temperatures in excess of

70 °C unless they are expressly permitted for higher temperatures.

Open the measuring instrument only when this is expressly described in the instruc-

tion manual for maintenance purposes.

Carry out only the maintenance and repair work that is described in the instruction

manual. Follow the prescribed steps exactly. For safety reasons, use only original

spare parts from Testo.

Any additional work must only be carried out by authorised personnel. Testo will

otherwise refuse to accept responsibility for the proper functioning of the measuring

instrument after repair and for the validity of certifications.

Ensure correct disposal:

Dispose of defective rechargeable batteries and spent batteries at the collection

points provided for that purpose.

Send the measuring instrument directly to us at the end of its useful life. We will

ensure that it is disposed of in an environmentally friendly manner.

A. Safety advice 7

B. Intended purpose

This chapter describes the areas of application for which the measuring instrument is

intended.

The testo 335 is a handheld measuring instrument used in professional flue gas analysis

for:

· Engineers servicing/monitoring industrial combustion plants (process systems, power

stations)

· Emissions inspectors

· Engine manufacturers and operators

· Service engineers/mechanics of burner/boiler manufacturers in the industrial sector

Typical measuring tasks and particular characteristics of the testo 335 include:

· Measurement on engines of all kinds (CO/NO dilution)

· Measurement on gas turbines (high precision CO and NO plus optional dilution)

· Emissions measurement (integrated flow speed and real moisture content

measurement)

testo 333 should not be used:

· for continuous measurements

· as a safety (alarm) instrument
