Phase-Shifting Stroboscopes - Model PB115

Dual-function delays in external mode  Delays adjustable as phase angle or time - resolution to 0.01° and 0.0001 seconds  Auto flash intensity maximizes brightness through entire range  External triggering from remote sensor or TTL compatible pulse  Non-volatile memory stores/recalls 3 full settings & last measurement  Auto blanking allows use of standard optical sensors in most applications without flash re-triggering  Operates continuously from internal rechargeable batteries or line power Supplied with NIST certificate

These new stroboscopes incorporate the unique design features of the Nova-Strobes (Cat. Nos. 21G20 and 21G21) plus having an increased operating range of 30 to 32,500 flashes per minute and phase shifting capability throughout the complete operating range. These units can multiply or divide the flash rate by two with the press of a button, quickly identifying the basic speed and harmonics. The digital adjustment knob can select the decade for adjustments, providing coarse and fine adjustments quickly and with better resolution than competitive units. Memory can store three frequencies to be stored, accelerating measurements that require the use of several different flash rates which can be displayed in either flashes per minute or per second. Internal rechargeable batteries are standard; an optional external battery pack is available for continuous operation from line power. Units are available for 115 and 230VAC power supply. Price includes a battery charger and instruction manual; kits include unit, carrying case, AC power supply, spare bulb and instruction manual.
