DRYING TIME RECORDER
A reliable apparatus to test the drying time or gelation behaviour of many paints and coatings,
The drying time is calculated from the distance travelled, measured using a graduated rule along the edge, corresponding to the various stages observed on the trace.
Automatically stops at the end of travel.
A needle carrier holding six hemispherical ended needles travels the length of the six 305 x 25 mm test strips in 6, 12 or 24 hours.
Features:
◆ Simple maintenance & easy to clean.
◆ Evaporation of solvent: deep pear-shaped impression.
◆ Sol-gel transition: continuous track.
◆ Surface dry: interrupted track.
◆ Final dry time, the needle no longer penetrates the film.
◆ 240 V/50 Hz or 110 V/60 Hz*.
The BK 3 Speed Drying Recorder has been used widely in the coatings industry throughout the world for several decades.
BK3: 6 tracks, 3 selectable speeds: 6, 12 or 24 h.
The BK 6 and BK 10 Recorders have independently operating tracks allowing tests to be made at different start times.
Pairs of tracks operate at the same speed, and a wide range of travel times are available. Travel times of 6, 12, 24 and 48 hours are all considered as standard. A time scale on the front cover is graduated to suit the instrument’s drying time ranges.
◆ Each pair of tracks has its own individual operating switch.
◆ BK6: 6 tracks, each pair of tracks is driven by an Independent motor
◆ BK10: 10 tracks, each pair of tracks is driven by an Independent motor
