Page 5: Certification Information
Operating Temperature and Humidity Limits The Biosystems PHD6’s operating temperature range is printed on the label on the back of the instrument. Use of Sperian Gas Detectors outside of the instrument’s specified operating temperature range may result in inaccurate and potentially dangerous readings. - Page 6 Sperian part number 54-49-103-5. The PHD6 must be located in a non-hazardous location during the charging cycle. Charging the PHD6 in a hazardous location may impair intrinsic safety. PHD6 rechargeable battery packs are supplied with Panasonic CGR18650D Lithium-Ion batteries. The Li-Ion batteries in the battery packs may not be replaced by the user.
