ULTRAPEN™ PT6 Measurement Modes: MODE METHOD OF MEASUREMENT Hold Displays real-time readings until the LED turns solid ON, then displays final readings. LIVE Displays real-time readings continuously for up to 5 minutes. ULTRAPEN™ PT6 Parameter Modes: MODE PARAMETER MEASURED N Display alternates between Nitrate as Nitrogen (NO3—N), and Temperature NO3 Display alternates between Nitrate (NO3—), and Temperature mV Display alternates between millivolt (mV), and Temperature ULTRAPEN™ PT6 Specifications: Specifications Nitrate as Nitrogen NO3—N Nitrate NO3— Temperature Ranges 1-1400 ppm 4.4-6200 ppm 0 – 71°C / 32 – 160°F Accuracy1 ± 10% of the reading ± 10% of the reading ± 0.1°C Resolution 0.1 ppm 0.1 ppm 0.1°C/F pH Range: 3-11 pH Time to Reading Stabilization: 10 – 180 seconds Power Consumption: Active Mode: 30 – 140 mA, Sleep Mode: 2 μA Physical Dimensions: 17.15 cm L x 1.59 cm D or 6.75 in. L x .625 in. D Weight: 54 g or 1.94 oz. Case Material: Anodized Aircraft Aluminum with Protective Coating Battery Type: N type, Alkaline 1.5 V Calibration Standard Solutions: 1, 10, 100, or 1000 ppm NO3—N Operating/Storage Temperature: 0-40°C / 32-104°F 2 Enclosure Ratings: IP67 and NEMA 6 EN61236-1: 2006 – Annex A: 2008; Electrostatic discharge to case of instrument may cause PT6 to spontaneously power ON. In this case, the PT6 will power OFF after several seconds. WARNING! These products can expose you to chemicals including Di(2-ethylhexyl)phthalate (DEHP), which is known to the State of California to cause cancer and birth defects or other reproductive harm.
