Ray-Ran Ohaus Pioneer Weighing Balance

Ray-Ran Ohaus Pioneer gives laboratories and industrial sites the fundamentals of routine weighing – clear readout, GLP/GMP data output, second-line guidance, and EC type-approved variants – without paying for touchscreen automation you would not use every day. 

Configurations

Semi-micro: 0.01 mg readability with 82 g and 220 g capacities. Stainless steel pan on Ø 80 mm platform. Glass draftshield. 

Analytical: 0.1 mg readability with capacities up to 220 g. Stainless steel pan on Ø 90 mm platform. 

Precision: 1 mg through 0.1 g readability with capacities up to 12 kg on the high-capacity model. Stainless steel pan across platform sizes from Ø 120 mm (1 mg models with glass draftshield) through Ø 180 mm and 193 x 248 mm (12 kg high-capacity PX12001 series). 

Interface and applications

Every Pioneer carries a backlit LCD with a second-line dot-matrix display for operator guidance, RS-232 and USB device interfaces with GLP/GMP-compliant data output and a real-time clock, and support for up to four operating languages. Applications on-instrument include basic weighing, parts counting, percent weighing, animal weighing, density determination, and formulation. A static removal bar helps stabilize readings for low-mass samples that would otherwise be affected by static, and up to two touchless sensors let operators tare or print without touching the balance. 

Sub-variants: Standard, /M, and /E

Three sub-variants let you match the balance to the job: 

Standard PX: includes Internal Adjustment (AutoCal on semi-micro models). The balance calibrates itself when it detects temperature drift, reducing manual calibration cycles and the risk of an out-of-spec reading between them. 

PX/M (EC Type Approved): adds EC type approval on top of the standard specification for legal-for-trade and prescribed applications. Verification interval (e) stated in the full spec sheet. 

PX/E (Economy): removes Internal Adjustment to hit a lower price point where manual span calibration is acceptable. Same LCD interface and application set. Available on analytical and precision only (no /E semi-micro variant). 

Why it matters

Compliant weighing at the entry price point: GLP/GMP-compliant data output with a real-time clock, plus EC type-approved (/M) variants for legal-for-trade or prescribed applications – available at Pioneer’s entry-tier price. 

One family across routine QC and teaching labs: same LCD platform and application set from 0.01 mg semi-micro through 12 kg high-capacity – one training program for R&D, production QC, and educational settings. 

Three price points, one application set: Standard for routine weighing; /M for legal-for-trade; /E where cost is the driver and manual span calibration is acceptable. 

Model range summary

30 models across three configurations. See the downloadable spec sheet for full detail. 

What happens after you inquire

A balance specialist will confirm your application, configuration, sub-variant (standard, /M, or /E), and IP SKU reference. If you need touchscreen operation, up to 3,000 sample libraries, or pharmaceutical audit-trail features, we will map your workflow to the Adventurer or Explorer range before you commit to Pioneer.
