After removing the cover, the environmental tester delivers reliable results in seconds. With a large measuring range of up to 200 klx or 20 kfc, the luxmeter offers a wide range of applications in different lighting environments.<\/p>\n<p>With the min-max hold value display, the environmental tester ensures that the most important values are not overlooked, while the temperature display provides additional information about the measuring environment. The luxmeter has an easy-to-read LC display. Up to 12 measured values can be stored and recalled in the internal memory.<\/p>\n<p>The automatic switch-off function prevents uncontrolled battery discharge. The environmental tester switches off automatically after 15 minutes when the lid is open and after one minute of inactivity when the lid is closed. An operating time of up to 60 hours can be achieved with standard AAA batteries.<\/p>\n<h3>Highlights<\/h3>\n<ul>\n<li>Measuring range up to 200 klx or 20 kfc<\/li>\n<li>Resolution from 0.1 lx<\/li>\n<li>Measuring accuracy: \u00b13 % + 8 digits<\/li>\n<li>MIN \/ MAX \/ HOLD<\/li>\n<li>Ambient temperature measurement<\/li>\n<li>Memory for 12 measured values<\/li>\n<\/ul>\n<h3>Technical specifications<\/h3>\n<ul>\n<li>Light \u2014 Measuring range: 0 &#8230; 999,9 lx<\/li>\n<li>Light \u2014 Resolution: 0,1 lx<\/li>\n<li>Light \u2014 Accuracy: \u00b1(3 % of Rd \u00b18 digits)<\/li>\n<li>Light \u2014 Measuring range: 1000 lx &#8230; 200 klx<\/li>\n<li>Light \u2014 Resolution: 1 lx<\/li>\n<li>Light \u2014 Accuracy: \u00b1(3 % of Rd \u00b18 digits) &lt;10,000 lx, \u00b1(4 % of Rd \u00b110 digits) &gt;=10,000 lx<\/li>\n<li>Light \u2014 Measuring range: 0 &#8230; 99,9 fc<\/li>\n<li>Light \u2014 Resolution: 0,01 fc<\/li>\n<li>Light \u2014 Accuracy: \u00b1(3 % of Rd \u00b18 digits) &lt;1000 fc, \u00b1(4 % of Rd \u00b110 digits ) &gt;=1000 fc<\/li>\n<li>Light \u2014 Measuring range: 100 fc &#8230; 20 kfc<\/li>\n<li>Light \u2014 Resolution: 0,1 fc<\/li>\n<li>Light \u2014 Accuracy: \u00b1(3 % of Rd \u00b18 digits) &lt;1000 fc, \u00b1(4 % of Rd \u00b110 digits ) &gt;=1000 fc<\/li>\n<li>Temperature \u2014 Measuring range: -20 &#8230; +70 \u00b0C<\/li>\n<li>Temperature \u2014 Resolution: 0,1 \u00b0C<\/li>\n<li>Temperature \u2014 Accuracy: \u00b11.5 \u00b0C<\/li>\n<li>Temperature \u2014 Measuring range: -4 &#8230; +158 \u00b0F<\/li>\n<li>Temperature \u2014 Resolution: 0,1 \u00b0F<\/li>\n<li>Temperature \u2014 Accuracy: \u00b12.7 \u00b0F<\/li>\n<li>General technical data \u2014 Measuring functions: MIN, MAX, HOLD<\/li>\n<li>Units lx, FC, \u00b0C, \u00b0F \u2014 Display type: LCD with backlight<\/li>\n<li>Units lx, FC, \u00b0C, \u00b0F \u2014 Display refresh rate: 2 x per second<\/li>\n<li>Storage medium Internal memory \u2014 Storage capacity: 12 Values<\/li>\n<li>Storage medium Internal memory: Operating time 60 h<\/li>\n<li>Storage medium Internal memory: Automatic power-off 15 min<\/li>\n<li>Storage medium Internal memory \u2014 Menu language: English<\/li>\n<li>Storage medium Internal memory \u2014 Protection class (device): IP20<\/li>\n<li>Storage medium Internal memory \u2014 (Rechargeable) battery: 2 x 1,5 V AAA battery , Alkali-manganese<\/li>\n<li>Storage medium Internal memory \u2014 Capacity: 1200 mAh<\/li>\n<li>Storage medium Internal memory \u2014 Operating conditions: -20 &#8230; 60 \u00b0C , 0 &#8230; 90 % RH<\/li>\n<li>Storage medium Internal memory \u2014 Storage conditions: -20 &#8230; 60 \u00b0C , 0 &#8230; 75 % RH<\/li>\n<li>Storage medium Internal memory \u2014 Dimensions: ( D x \u00f8 )31 x 80 mm<\/li>\n<li>Storage medium Internal memory \u2014 Weight: 90 g<\/li>\n<\/ul>\n<h3>Delivery scope<\/h3>\n<ul>\n<li>1 x PCE-LM 4 Promotion<\/li>\n<li>1 x case<\/li>\n<li>2 x 1.5 V AAA battery<\/li>\n<li>1 x operating instructions<\/li>\n<\/ul>\n<h3>Documents<\/h3>\n<ul>\n<li><a href=\"https:\/\/pim.pce-service.net\/upload\/files\/assets\/pce-instruments-s662a1e1cc5d6a073.pdf\">Supplier document<\/a><\/li>\n<li><a href=\"https:\/\/www.pce-instruments.com\/eu\/api\/getartfile?_fnr=6153105&amp;_dsp=inline\">Supplier document<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Environmental Tester with internal sensor \/ measuring range 0 lx &#8230; 200 klx \/ Temperature measurement \/ Internal memory for up to 12 values \/ Units: lx, fc, \u00b0C, F \/ Min-Max-HOLD display.
